Baseline ECG recordings were acquired with radiotelemetry in eight young (14-wk-old) and eight aging (55-wk-old) SHRs and in two groups of four age-matched Wistar-Kyoto (WKY) rats. Quantificati...

The autonomic nervous system plays an important role in the genesis of various cardiac rhythm disorders. Experimental studies have indicated that in atrial fibrillation particularly vagal activity may have a decisive influence on the electrophysiologic properties of atrial myocardium. In patients with paroxysmal atrial fibrillation, a carefully taken history and electrocardiographic findings ob...
