Standard ADC components seldom provide enough flexibility to meet the conflicting needs of today’s medical designs. By Ian ...

The rhythm is irregular, but there is a pattern. All of the long RR intervals are the same (1.16 sec), the intermediate RR intervals are the same (0.64 sec), and the short RR intervals are the same (0 ...

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 ...

The diagnosis is sinus rhythm, with acute inferior wall ST-segment elevation myocardial infarction (STEMI), ventricular triplet (nonsustained monomorphic VT), premature ventricular complex, R-on-T ...

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 94-year-old female with history of hypertension, chronic kidney disease, and hyperlipidemia presents to the emergency ...

This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...

Researchers at University Medical Center Maastricht and international partners report that a single shot of the drug ...

A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...

Dr. Nino Mihatov: A 52-year-old woman was evaluated for a new wide-complex tachycardia that developed while she was hospitalized for the management of seizures. Five days before the development of ...
