The correct diagnosis is normal sinus rhythm, V1-V3 lead switch (Figure 2). This is an example of sinus rhythm with V1-V3 lead switch. The rhythm is regular at a rate of 95 beats/min. There is a P ...
Wide complex tachycardia is a general term that refers to conditions that cause an unusually fast heart rate and a particular pattern on an EKG. Tachycardia is when your heart beats unusually fast, ...
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS ...
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 ...
There are P waves (+) with regular PP intervals and a rate of 85 beats/min. The P waves have a normal morphology; they are positive in leads I, II, aVF, and V4-V6. This is a stable normal sinus rhythm ...
Cardiac-resynchronization therapy (CRT) reduces morbidity and mortality in chronic systolic heart failure with a wide QRS complex. Mechanical dyssynchrony also occurs in patients with a narrow QRS ...
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 ...
