Heart Disease

Multifocal atrial tachycardia is a tachycardic version of wandering atrial pacemaker in which the atrial rate is greater than 100 beats per minute.

The ECG findings in Takotsubo cardiomyopathy ― also known as stress-induced cardiomyopathy, broken-heart syndrome or apical-ballooning syndrome ― are nonspecific, meaning there is not one typical ECG appearance to diagnose this disease.

An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes.

If the limb lead that was supposed to be attached to the right arm is put on the left arm — and vise-versa — a characteristic appearance will be seen on ECG that includes:

A prolonged QT interval has a variety of causes and can be a very serious ECG finding, as it may lead to the potentially fatal arrhythmia polymorphic ventricular tachycardia (Torsades de Pointes).

A trifascicular block is the combination of a right bundle branch block, left anterior or posterior fascicular block and a first-degree AV block (prolonged PR interval).
