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 normal sinus rhythm, interpolated premature ventricular complexes (PVCs) in a trigeminal pattern, retrograde concealed conduction, intraventricular conduction delay, and old inferior ...
The diagnosis is normal sinus rhythm, first-degree AV block (prolonged AV conduction), premature ventricular complexes, escape junctional complex, left ventricular hypertrophy with associated ST-T ...
THE electrocardiographic picture of prolonged QRS-complex duration with short PR interval was the subject of isolated reports 1,2 until Wolff, Parkinson and White 3 described the clinical syndrome of ...
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 ...
