What Does an Abnormal ECG Mean? Next Steps After Your Test
The health of any individual can be determined conveniently and without pain when the electrical waves propagating in the heart are measured and recorded. This process is called an electrocardiogram, or ECG. These waves cause movement within the heart as they tell the heart muscles to squeeze to push the blood into the body.
Sometimes, a doctor may request an electrocardiogram (ECG) to evaluate such signals and determine whether the heart is healthy. Today, let's discuss abnormal ECG results.
Identifying and Explaining Abnormal ECG Results on the Right Why Do Patients Get An Abnormal ECG?
Ninety-nine per cent of a normal person’s electrocardiogram (ECG) will display an even flat-lining in the electrical potential of the heart. When obtaining a lead in asinine electrocardiograph (ECG) the heart rate is likely to be within normal limits, that is between 60- 100 beats per minute. However, there are scenarios where some electrocardiogram (ECG) readings can be termed abnormal whereby such readings may show indicators like arrhythmias, disorders in conduction or variations of different levels of signals.
An ECG, or electrocardiogram, is a yardstick for assessing heart activity. Usually in situations when it is not even part of the presenting complaints. Most abnormal ECGs show abnormal heart rate, arrhythmias, or signs of ischaemia that suggest that some regions of the heart do not get adequate blood supply. Depending on the findings, each of these signs could mean a certain heart disease or another disorder, which could be mild or severe.
The Most Common Abnormal Findings
Arrhythmias
Arrhythmias is the term that is used to refer to all abnormal heart rhythms, which means the heart can either beat too fast, too slow, or at uncoordinated patterns. This includes both atrial fibrillation (AFib), where there is an irregular heartbeat, and Bradycardia, where the heart rate dips below 60 beats per minute.
Ischaemic Changes
These types of changes suggest a reduction of blood flow to the heart muscles. This is usually a result of some obstruction of the arteries or some other issues concerning the blood supply. This is often seen together with coronary artery disease and other diseases.
Left ventricular hypertrophy (LVH)
LVH however gives the impression that the left heart is bigger than the right heart. This is most often caused by hypertension, which then causes the heart to work harder.
Heart Block
A heart blockage is an obstruction or a break in the conduction pathways of the heart. There are different types of heart blocks, from first-degree, which is the least severe, to third-degree, where the block is complete and no signal gets to the ventricles. Heart blocks are associated with low heart rates; hence, seeking medical attention for this is very vital.
Causes of Deviations from Normal ECG Readings
Conditions Associated with the abnormal heart rhythm and abnormal ECG Results can suggest several heart-related conditions, such as:
1.CAD or Coronary Artery Disease:- is a clinical condition characterised by lowered oxygen and blood flow due to the narrowing or occlusion of vessels that supply blood to the heart.
2.Congestive Heart Failure:- A condition that refers to the failure of the heart to pump sufficient blood, which can readily be detected in an ECG through variation in electrical function and rhythm.
3.Myocardial Infarction:- Myocardial infarction is generally known as a heart attack. This occurs when the flow of blood to the heart is obstructed. An ECG can show the signs of a heart attack at present or prove that a heart attack has already taken place.
Non-Heart-Related Factors
Moreover, there are several non-heart-related causes that can also affect the ECG:-
-
Electrolyte abnormalities:- Such serum electrolytes such as potassium, calcium, and magnesium when dysregulated in the body may impact the cardiac electrical activity and hence distorted cycle-grams.
2. Effects from medications:- Some drugs may cause changes in the EKG, particularly those that modulate blood intoxication or the heart itself.
-
Stress:- Changes in heart rate and rhythm that can be due to emotional or physical stress can be analysed with the help of an electrocardiogram (ECG).
Next Steps After an Abnormal ECG
Consult Your Physician Once you get the abnormal ECG results, the first thing that you should do is see your physician. It is important to note that an abnormal ECG does not always mean that there is an underlying problem with the heart. After assessing your test, your doctor might ask for some details regarding the conditions that are troubling you as well as a few of your medical histories.
Further Testing
Your physician may advise further tests to understand more about your heart based on the following findings.
-
The echocardiogram:- This study utilises ultrasound to take pictures of the heart to assess cardiac structures and internal cardiac valves and muscles for abnormality.
2. The Holter Monitor:- a 24-hour patient-worn device that long-term records the electrical activity of the heart. This is useful when seeking to diagnose disorders such as intermittent arrhythmias.
3. The Stress Test:- This is a test where the heart is observed as a person exercises to assess the capacity of the heart to cope with exertion. This may fail to identify problems with the heart even when the person is in a resting position.
Management and Monitoring
Depending on the underlying cause of an abnormal ECG pattern, your physician may recommend several interventions. For example:-
1.Medicines available for prescription:- Aids such as anticoagulants, antiarrhythmics, and beta-blockers may be used to balance out heart rhythm, reduce blood pressure, and lower chances of clot formation.
2.Alterations in lifestyle:- From the use of salt to the smoking habit or lack of exercise, all these have a negative impact on the heart condition, and thus putting them into practice will greatly assist in controlling the heart condition.
3. The Processes :- The "Processes" Case in point, the inclusion of a pacemaker, conducting an angioplasty, or performing surgery could be required in some instances to manage and repair the ailment of the heart.
When to Seek Immediate Medical Help?
This is because some signs should never be dismissed or taken easily because they could mean something dangerous is going on that needs medical help right away. Those things are:
1.Chest pain :- Any chest or lung-related pain, particularly sudden and acute-onset chest pain, should be regarded with the highest level of emergency as it may connote an impending heart attack.
2. Shortness of Breath:- Struggling for breath occurs and sets in without any known cause, seek immediate medical attention so that heart problems can be ruled out.
3. Extreme Dizziness or Fainting:- Causeless and extreme fainting accompanied by dizziness should cause concern because such occurrences coupled or apart can be signs of irregular heartbeat behaviours.
Conclusion
The bottom line, an abnormal ECG reading can mean many things – some trivial and others signalling serious heart problems. Even though results that aren't normal can be very scary, it's important to remember that many heart issues can be well managed. So, you need to be careful about any shortness of breath and any coronary artery disease down the line.
FAQs
What do abnormal ECG results mean?
Abnormal findings in an ECG test are those that depict any deviation from the normal electrical activity of the heart. This includes the presence of arrhythmias such as tachycardia or atrial flutter, heart rate changes, and variations in the morphology of electrical axes in the heart (P wave, QRS wave, T wave). Some abnormalities, however, can be benign and temporary or may not cause any problems at all.
Will I be advised to worry if the ECG is abnormal?
Some people also think that all "abnormal ECGs" need to be taken seriously, which is not true. A lot of these abnormalities aren't serious or only last a short time, but some may need to be looked into because they point to problems that go deeper than heart function. If this kind of test is done as part of a regular check-up, the doctor will usually analyze the results and either say that the differences aren't important or that they are caused by something like "heart disease." It's best to know what's going on and wait for the "physician" to send you for any tests that may be needed before you try to fix yourself.
What to do if there is an ECG abnormality?
The average course of action in most cases where the electrocardiogram is found to be abnormal involves contacting ‘your doctor’ for a more comprehensive verification of the findings. As a follow-up to the abnormal findings, your doctor may order "an echocardiogram, which uses ultrasound to show the heart's structures; a Holter monitor, which is an ECG device worn for long periods; or a stress test, which checks the heart while it's working hard."
Has an abnormal ECG ever worried you?
It's important to note this warning; in some cases, an increased ECG shouldn't always be taken as a sign of a serious risk. Changes can be seen on an ECG in less dangerous cases, like when someone is stressed, taking certain medications, or even when electrolyte problems are fixed. It is best to consult your doctor to determine the reason for the irregularity and whether you need to change your lifestyle to be heart-healthy.
What does it mean if the ECG changes are abnormal?
A bad ECG indicates unusual cardiac electrical activity. This might be clear in several situations, including the reasons and signs of ischemia, arrhythmias, or changes in the heart's structure like LVH. It is also smart to keep in mind that not all of these strange things are frightening. Some may be innocent or situational. No, to fully appreciate what an “abnormal ECG" means, one has to seek a physician’s counsel.
What is the most commonly seen abnormality in the ECG?
The find is referred to as “Atrial Fibrillation” or AFib and is one of the most common ECG abnormalities which if not resolved could lead to a stroke or blood clot. There are two other abnormalities, ‘Bradycardia’ a slow heart rate and ‘Premature Ventricular Contraction’ which is an extra heartbeat that begins in the lower parts of the heart. There can be different degrees of how serious these ailments may get, however with the appropriate diagnosis and management, most people with these conditions can lead a healthy ‘heart’ life.
