The upper limits of normal for positive T wave amplitude are 0.5mV (5mm on a standard ECG) in the limb leads and 1.0mV (10mm) in the precordial leads. The first ECG abnormality noted during an ST segment銆唋evated myocardial infarction (STEMI) may actually be something other than the ...

Brugada Syndrome is an ECG abnormality with a high incidence of sudden death in patients with structurally normal hearts. Brugada syndrome is due to a mutation in the cardiac sodium channel gene. This is often referred to as a sodium channelopathy. Over 60 different mutations have been described...
The P waves are abnormal, and they are tall, narrow, and peaked inleads II, aVF, and V1-V2. The P-wave morphology is characteristic ofaP pulmonale, a result ofright atrial hypertrophy. This may also betermed ari...
A dysfunction of the autonomic tone can often be suspected as a cause of the abnormality, especially in the groups with tachycardia, T wave changes, AV block grade I and AV junctional rhythm. An ECG recording during orthostasis was considered to be of value to clarify the nature of the ECG...

ST segment abnormality – Choose one. T wave abnormality – Choose one. Right ventricular hypertrophy – Choose one. Left ventricular hypertrophy – Choose one. Patterns of previous myocardial infarction – Choose one. Patterns of complete bundle branch block – Choose one....
Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...
