An 83-year-old retired biochemistry professor was found by his wife unresponsive in his bathtub approximately 60 min after their last conversation. She found him lying upright in the empty bathtub, wearing pajamas with his arms folded across his chest. When emergency medical services arrived, he was hypopneic, with a barely palpable pulse and no measurable BP. En route to the hospital, pulseless electrical activity developed for which he received chest compressions, IV epinephrine (1 mg) and atropine (1 mg), with return of spontaneous circulation after < 10 min of resuscitation. The patient’s medical history was notable for ischemic cardiomyopathy and a recent stroke that diminished his functional capacity, although he remained able to perform most activities of daily life.
