There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all the ...

This ECG meets two criteria for ventricular tachycardia. AV dissociation appears to be present. Examine the rhythm strip in lead V1 and intermittently a P wave will correspond just prior to the QRS ...

This rhythm strip was taken from a 41-year-old male with lymphoma. He had a 5-day history of substernal chest pain, which was increased by lying down and decreased by sitting up and leaning forward.

An arrhythmia is an atypical heartbeat that is either much faster or slower than expected. Your heartbeat may be described as chaotic, rather than steady and predictable. There are several types of ...

There is clearly a broad QRS complex which is predominantly positive in V1 indicative of RBBB. You can also see an RSR pattern to the QRS complex in V1 reflective of the fact that the left ventricle ...

Arrhythmia and dysrhythmia are terms that both describe an abnormal heart rate or rhythm, with arrhythmia being the more commonly used term. An abnormal heart rate can be either faster (tachycardia) ...

An arrhythmia (pronounced as “uh-RITH-me-uh”) is an irregular heartbeat. This means your heart is out of its usual rhythm. About 1.5%-5% of people have arrhythmias. It may feel like your heart skipped ...
