Pacemaker Limitation of Tachycardia in Hypovolemic Shock
A 49-year-old white man was admitted to the emergency department with nausea and diarrhea of 11 hours duration. He had experienced crampy abdominal pain as well. He reported that his stools had been dark and malodorous. He had no prior history of gastrointestinal disorders, nor travel, unusual oral or liquid intake. There was a remote history of alcohol abuse, but no hepatitis or cirrhosis. Rec...
متن کاملTachycardia in the presence of a pacemaker.
A 84 year old woman was admitted with palpitations of a few days' duration. She had a dual chamber permanent pacemaker (DDD) fitted five years ago for complete heart block. She was tachycardic with a heart rate of around 120 beats/min but haemodyna-mically stable. A rhythm strip is shown below (see fig 1). QUESTIONS (1) What is the electrocardiographic diagnosis? (2) Is the pacemaker malfunctio...
متن کاملTachycardia-induced unexpected pacemaker behaviour
At the beginning of the recording, atrial tachycardia (AT) can be observed with 1:1 conduction at ventricular rate 140 bpm (upper track). At the spontaneous termination of the tachycardia, atrial-ventricular pacing at 45 bpm (lower rate) and after two cycles atrialventricular pacing at 100 beats/min (upper track) can be observed. The rate drop response was activated: drop size 25 ppm, drop rate...
متن کاملReversion of ventricular tachycardia by pacemaker stimulation.
Reversion of ventricular tachycardia to either sinus rhythm or atrialfibrillation has been achieved in a group ofpatients by rapid ventricular pacing. The standard technique involved pacing at a rate slightly in excess of the existing tachycardia until ventricular capture was achieved. Cessation ofpacing after afew seconds was usuallyfollowed by a supraventricular rhythm, though pacing at a low...
