In the present study, our first aim was to assess the capability of body surface potential mapping (BSPM) QRS area analysis for detection and quantification of pressure overload-induced LVH compared ...

The rhythm is irregular, but the long intervals are the same (↔) and the short intervals (┌┐) are the same. One premature QRS complex (↑) is observed. Therefore, the rhythm is regularly irregular. The ...

The diagnosis is sinus tachycardia, right ventricular pacemaker, P-wave synchronous ventricular pacing (A-sensed V-paced), pseudo second-degree AV block due to failure of atrial sensing. There is a ...

The QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...

A 47-year-old man with chronic schizophrenia was hospitalized after prolonged hypothermia. The initial electrocardiogram revealed Osborn waves (arrowheads) similar in amplitude to the R waves.

A 90 year old male with no past medical history to clinic with a complaint of generalized weakness, dizziness, and dyspnea on exertion. Mild lower extremity edema, paroxysmal nocturnal dyspnea, and ...
