The rhythm is regular at a rate of 78 beats/min. Before each QRS complex, there are two pacing stimuli (+,v) with a very short interval (0.06 sec) between them. They are both ventricular pacing ...

Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function. In this study, we examined whether biventricular pacing is ...

February 4, 2004 — Is it time to redefine the role of QRS duration as a predictor of response to cardiac resynchronization therapy (CRT)? According to 2 recent studies published in the Journal of the ...

Right ventricular pacing restores an adequate heart rate in patients with atrioventricular block, but high percentages of right ventricular apical pacing may promote left ventricular systolic ...

What type of pacemaker does the patient have? This ECG is from a patient with a biventricular pacemaker. If the ventricular pacing is originating in the right ventricle like a normal pacemaker, a left ...

Please provide your email address to receive an email when new articles are posted on . SAN FRANCISCO — His bundle pacing as first-line therapy did not improve ECG or echocardiographic parameters ...

Researchers at Texas Heart Institute (THI) and UCLA crossed a significant milestone in the development of wirelessly powered, leadless pacemakers. In an article in the Nature Research journal ...

Patients with indications for cardiac resynchronization therapy (CRT) have better clinical outcomes when they undergo left bundle branch area pacing (LBBAP) rather than conventional biventricular ...
