Sinus bradycardia was more frequent in athletes. All control subjects were in sinus rhythm whereas 0.9% of the athletes had other rhythms (nodal, coronary... Bjø,H Rnstad,L Storstein,... - 《Cardiology》 被引量: 42发表: 2008年
Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats per minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats per minute. The action potential responsible for this rhythm arises from the sinus...

TREATMENT OF SINUS BRADYCARDIA AND AV JUNCTIONAL RHYTHM WITH TRANSESOPHAGEAL ATRIAL PACING: HEMODYNAMIC EFFECTS OF PACINGTransesophageal atrial pacing (TAP) with the use of standard, thermistor-equipped, esophageal stethoscopes, modified for pacing by incorporation of a 4-French, bipolar TAP pr...
Sinus bradycardia is sinus rhythm with a rate less than 60 beats/min (Fig. 20-1).* Each QRS complex is preceded by a P wave; the P wave is negative in lead aVR and positive in lead II, indicating that the sinoatrial (SA) node is the pacemaker. Some patients may have a sinus brad...

The drugs can, through their β1-adrenoceptor blocking activity, elicit potentially dangerous alterations in heart rate and rhythm in patients with existing sinus bradycardia or arrhythmias (that is, second- or third-degree atrioventricular block).60,62 Development of symptomatic bradycardia on topical ...

Results: During sinus rhythm, mean ventricular rate was 72 + 7 bpm. Device diagnostics showed AT episodes longer than 5 minutes in 253 (73%) patients and at least one day with 24 hour consecutive AT in 156 (45%) patients. In this sub-group of 156 patients, mean VR was higher than ...
