Does the incidence of cardiac arrhythmias differ between patients in the chronic phase of cerebral infarction versus cerebral hemorrhage?
Does the incidence of cardiac arrhythmias differ between patients in the chronic phase of cerebral infarction versus cerebral hemorrhage?
Supraventricular arrhythmias are significantly more common in the chronic phase of cerebral infarction compared to cerebral hemorrhage, highlighting their potential role as a risk factor or trigger for ischemic stroke.
Association of atriopathic arrhythmias with chronic cerebral infarction is hypothesis-generating; prospective studies needed before considering screening or intervention.
Eighty-eight stroke patients, 52 with cerebral infarction and 36 with cerebral hemorrhage, underwent continuous cardiac rhythm monitoring at least five months after the onset of the acute incidents.The incidence of ventricular arrhythmias were almost the same in the patients with cerebral infarction (23.1%) and in those with cerebral hemorrhage (22.2%). But atriopathic arrhythmias were more frequent in the patients with cerebral infarction (48.1%) than in those with cerebral hemorrhage (16.7%). The difference was highly significant (p < 0.01). Both sporadic atrial premature beats and episodes of atrial tachyarrhythmias (short episodes of paroxysmal atrial tachycardia or transient atrial fibrillation) were more frequent with cerebral infarction. The high incidence of atriopathic arrhythmias was postulated to be causally related to the cerebral infarction.
