Many cerebral strokes are due to undetected cardiac arrhythmias. Any rapid cardiac arrhythmia may induce neurological symptoms as hemiplegia, aphasia, or psychosis. Twenty-eight patients who developed neurological disturbances following various cardiac arrhythmias were carefully studied. Most of these were due to rapid atrial fibrillation or supraventricular tachycardia. Undetected bradycardia due to vagotonia was a common cause of transient episodes of unconsciousness.
The cerebral blood flow was measured in animals when cardiac arrhythmias were induced. It was noted that frequent premature systoles reduced the cerebral blood flow 7 to 12%. More frequent runs of premature systoles caused a greater reduction. Supraventricular
