Medical Clinics of North America, 1984
The spectrum of cardiac arrhythmias that may be encountered in paced patients is vast; as multiprogrammable and dual-chamber pacemakers have become more sophisticated, the problems of electrocardiographic interpretation have multiplied. The arrhythmias may be broadly classified as follows: those due to abnormal functioning of the device, those due to ...

Physiologic Pacing: New Modalities and Pacing Sites
Pacing and Clinical Electrophysiology, 2006Right ventricular (RV) apical pacing impairs left ventricular function by inducing dyssynchronous contraction and relaxation. Chronic RV apical pacing is associated with an increased risk of atrial fibrillation, morbidity, and even mortality. These observations have raised questions regarding the appropriate pacing mode and site, leading to the ...

Idiosyncratic Pacing with a Commercial Pacing System Analyzer
Pacing and Clinical Electrophysiology, 1997An idiosyncratic response of the Medtronic AV Pacing System Analyzers (models 5311 [unipolar] and 5311B [bipolar]) during high output AAI pacing is reported. Using the bipolar analyzer with unipolar cables and a 2734 adaptor, ventricular capture was noted during high output AAI pacing when the ground was displaced from the patient.

Pacing and clinical electrophysiology : PACE, 2018
His‐bundle (HB) pacing is the most physiological method of ventricular pacing. However, it is also considered a demanding procedure with a low success rate and has suboptimal pacing parameters.

Advances in cardiac electrophysiology have clarified some of the mechanisms of tachydysrhythmias and have characterized tachycardias that are amenable to pace termination. Tachydysrhythmias most likely to be terminated by pacing techniques tend to be slow, re-entrant tachycardias.

Vasovagal Syncope: To Pace or not to Pace?
2000Most patients with vasovagal syncope faint infrequently and require only reassurance and advice about dietary and lifestyle modifications. However, there is a minority of patients who are considerably more distressed. Patients with recurrent vasovagal syncope may seriously injure themselves, may not be able to drive a car or to perform their jobs, and ...

Left Ventricular Endocardial Pacing/Leadless Pacing
Cardiac Electrophysiology Clinics, 2019Several clinical trials have established the role of cardiac resynchronization therapy in patients with heart failure, impaired left ventricular function and dyssynchrony. Challenges to traditional therapy include coronary sinus anatomy and failure to respond.

Currently most implanted pacing and defibrillation systems monitor and treat inappropriate cardiac rhythms. In general, these inappropriate rhythms result in cardiac outputs that are inadequate to meet metabolic demands, and thus can be life-threatening.
