Pacemaker Channels

Annals of the New York Academy of Sciences, 2004
Abstract: The pacemaker “funny” current (If) has been the object of detailed investigations since its original description in sinoatrial node myocytes in the late 1970s; its role in underlying generation of spontaneous activity and autonomic modulation of cardiac rate has been amply demonstrated.

Pacemakers

Current Problems in Surgery, 1997
Rapid advances in pacing technology will continue to affect the quality of life of many patients with cardiovascular disease. A truly "smart" device that seemed fanciful 30 years ago now seems to be a virtual certainty by early in the next century.

Pacemaker automaticity

The American Journal of Cardiology, 2000
The automated measurement of the main electrical parameters of pacemakers, such as battery voltage, current drain, pacing impedance, sensing levels, and pacing thresholds enables a continuous monitoring of the adequate functioning of the implanted device.

Pacemaker Malfunction

Annals of Internal Medicine, 1993
The field of cardiac pacing has expanded rapidly in recent years. Engineering improvements and microprocessor technology have resulted in a vast increase in pacemaker technology. The "high-tech" edge of cardiac pacing often discourages all but the pacemaker specialist from approaching a malfunctioning pacemaker.

Transcutaneous pacemakers

The Journal of Cardiovascular Nursing, 1991
Transcutaneous pacing (TP) is technically the fastest, easiest, and least physically invasive of the accepted modes of cardiac pacing. Although first introduced in the early 1950s, TP was abandoned because of cutaneous nerve pain, skeletal muscle contraction, and local tissue burns associated with the use of the technique.

Pacemaker Headaches

Pacing and Clinical Electrophysiology, 1984
A symptom complex (Pacemaker syndrome) consisting of hypotension, dizziness, or near‐syncope in patients with functioning ventricular pacemakers has been previously described. Whereas, the effects of synchronized ventriculo‐atrial contraction on forward systemic circulation are known, the effects of increased venous dynamics on systemic function are ...
