First Claim
Patent Images
1. An atrial cardioverter comprising:
- a pacemaker for applying atrial pacing pulses to an atrium of a heart;
an atrial tachyarrhythmia detector for detecting an atrial tachyarrhythmia of the heart;
an R wave detector for detecting R waves of the heart; and
a cardioverting stage including a timer for timing time spans alternatingly between immediately successive R waves and subsequent atrial pacing pulses and between immediately successive atrial pacing pulses and subsequent R waves for applying cardioverting electrical energy to the atria of the heart responsive to such a time span exceeding a predetermined duration.

Abstract
An atrial cardioverter which includes a pacemaker for applying atrial pacing pulses to an atrium of a heart, an atrial tachyarrhythmia detector for detecting an atrial tachyarrhythmia of the heart, and an R wave detector for detecting R waves of the heart. A cardioverting stage including a timer for timing time spans between immediately successive R waves and atrial pacing pulses applies cardioverting electrical energy to the atria of the heart responsive to a time span exceeding a predetermined duration.
