Physiologic VDD versus Nonphysiologic VVI Pacing in Canine 3rd-Degree Atrioventricular Block

Physiologic dual chamber pacing in radiation-induced atrioventricular block.

Pacing for atrioventricular block.

to the editor: The report by Toff and colleagues on the United Kingdom Pacing and Cardiovascular Events (UKPACE) trial (July 14 issue), 1 evaluating cardiovascular end points in elderly patients with atrioventricular block, showed that the use of dual-chamber pacing to maintain atrioventricular synchrony conferred no survival advantage over the use of single-chamber pacing. These results may be...

Second-degree atrioventricular block type II and third-degree atrioventricular block requiring cardiac pacing after tooth extraction

Because atrioventricular block can cause cardiovascular collapse, the rapid management of this condition is necessary. An 82-year-old man complained of discomfort after tooth extraction, and electrocardiography showed second- and third-degree atrioventricular blocks. Dentists should monitor patients who report discomfort using electrocardiography because of the possibility of life-threatening a...

Second-degree atrioventricular block.

1) While it is possible only one type of second-degree AV block exists electrophysiologically, the available data do not justify such a conclusion and it would seem more appropriate to remain a "splitter," and advocate separation and definition of multiple mechanisms, than to be a "lumper," and embrace a unitary concept. 2) The clinical classification of type I and type II AV block, based on pr...

Is VVI pacing outmoded?

Pacing is a common clinical procedure. The permanent implant rate in the United Kingdom is lower than in other Western countries. The last World Survey' showed a new implant rate of 148 per million population per year (8346 systems) in the United Kingdom. This compares with 421 in Germany, 413 in France, 359 in the United States, and 175 in Spain. In the United Kingdom, the pacing mode was simp...
