Patent foramen ovale with right to left shunt as a cause of hypoxia without Eisenmengers physiology or with only moderately pulmonary artery pressures is an uncommon presentation. Initial diagnosis via transesophageal echocardiography requires detection of a shunt with either color Doppler or agitated saline contrast with or without Valsalva maneuver. This rare but diagnosable case presented wa...
Rapid alternating intrathonicic pressure changes caused by rapid breathing with partial obstruction to airflow caused a three to four fold increase in forearm blood flow whereas following the Valsalva maneuver the blood flow was decreased. Evidence is presented that these changes are brought about reflexly through alterations in vasoconstrictor tone. It is deinontrated that the reflex changes a...
This report describes inhibition of a normally functioning bipolar demand pulse generator by diaphragmatic myopotentials. Transient pacemaker suppression occurred repeatedly with deep respiration, straining, the Valsalva maneuver, coughing, sneezing and laughing. When the magnet was applied, none of these maneuvers inhibited the pacemaker. Extensive investigations ruled out an intermittent elec...
