As a medical professional with expertise in cardiology, I can provide you with an overview of the various factors that can lead to an abnormal EKG. An electrocardiogram (EKG) is a crucial diagnostic tool that records the electrical activity of the heart. While an EKG abnormality can sometimes be a benign variation, other times it can indicate a serious medical condition. Here are some potential causes for an abnormal EKG: 1. Heart Attack (Myocardial Infarction): Damage to the heart muscle can cause changes in the EKG readings. 2. Heart Disease (Coronary Artery Disease): Narrowing of the arteries can lead to abnormal EKG patterns. 3. Cardiomyopathy: A disease of the heart muscle that affects its size, shape, or function, which can be reflected in the EKG. 4. Arrhythmias: Irregular heartbeats, such as atrial fibrillation or ventricular tachycardia, can cause EKG abnormalities. 5. Valvular Heart Disease: Problems with the heart's valves can alter the EKG. 6. Electrolyte Imbalances: Abnormal levels of sodium, potassium, or calcium can affect the heart's electrical activity. 7. Hyperthyroidism: An overactive thyroid can increase the heart rate and cause an abnormal EKG. 8. Certain Medications: Some drugs can affect the electrical conduction in the heart and lead to an abnormal EKG. 9. Physical Stress or Anxiety: Intense stress or anxiety can temporarily alter the EKG. 10. Inflammation or Infection: Conditions like myocarditis can cause EKG changes. 11. Pulmonary Embolism: A blockage in the lungs can affect the heart's electrical activity. 12. Congenital Heart Defects: Some people are born with heart defects that can show up on an EKG. It's important to note that not all EKG abnormalities are clinically significant. A thorough medical evaluation, including a review of the patient's medical history and symptoms, is necessary to determine the cause and appropriate treatment. read more >> -

An electrocardiogram (EKG) measures your heart's electrical activity. ... Sometimes an EKG abnormality is a normal variation of a heart's rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.read more >>+119962015-3-16
