Bradycardia, with Intermittent Albuminuria

Tachycardia-dependent versus bradycardia-dependent intermittent bundle-branch block.

Analysis of I6 cases with intermittent bundle-branch block showing rate-dependence revealed the presence of 12 instances with tachycardia-dependent bundle-branch block, 3 with bradycardiadependent bundle-branch block, and one instance showing both types at two different occasions. Tachycardia-dependent bundle-branch block was explained on the basis of cycle length-recovery time relation and rev...

Sinus bradycardia with cardiac asystole.

A case of sinus bradycardia with cardiac asystole was described in this journal (Pearson, 1945). The subsequent history and the post-mortem findings are now recorded. The patient was a woman aged 52 years who had been under observation since February 1943. Her pulse rate varied between 16 and 30 and her main symptoms were attacks of unconsciousness, resembling Stokes-Adams attacks; these were s...

Bradycardia

Profound bradycardia with decreased PEEP.

An athletic 21-year-old male was admitted to the surgical ICU after sustaining 2 stab wounds to his torso. He had an episode of left lung collapse early in his course, managed with suctioning and increased PEEP, to 15 cm H2O. He was bradycardic (heart rates 50-60 beats/min) throughout his ICU stay, but when the PEEP was lowered to 5 cm H2O in preparation for extubation, he developed sinus pause...

Neuromodulation of Limb Proprioceptive Afferents Decreases Apnea of Prematurity and Accompanying Intermittent Hypoxia and Bradycardia

BACKGROUND Apnea of Prematurity (AOP) is common, affecting the majority of infants born at <34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH). Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP), injury to sympathetic ganglia regulating cardiovascular action, impai...
