Popis: | Chronic hypertension can cause atrial fibrillation. The cellular mechanisms responsible for hypertension-induced atrial tachyarrhythmias, however, are unknown. Here we tested the hypothesis that, in spontaneously hypertensive rats (SHR), altered atrial Ca homeostasis may induce atrial tachyarrhythmias.At 6-8 months of age, SHR had significantly increased systolic blood pressure (185±6 mmHg, N=18; vs WKY: 129±4 mmHg, N=16, P |
