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 ...

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 ...

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 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 ...

Can quantum physics help to diagnose schizophrenia and depression? A paper just published in the Journal of Nervous and Mental Disease claims that a technique called 'quantum resonance spectroscopy' ...

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.

If it’s important that an ECG is done, it’s important that it’s legible. Asking patients to hold their breath for a couple of seconds can help, or if fine tremor is a problem, try moving the limb ...

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 ...
