A Smartwatch Heart Rate Monitor Prompts an Unusual Diagnosis

JACC: Case Reports, 2020
We report the case of a 54-year-old woman who presented for cardiological evaluation having noted a decline in her heart rate on her wearable heart rate monitor. She was found to be in 2:1 atrioventricular block.

FLUDARABINE-INDUCED BRADYCARDIA IN ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION

Hematology, Transfusion and Cell Therapy
Objective: Fludarabine, a purine analog, is getting more attention with the increasing use of reduced intensive conditioning regimens in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Bradycardia was observed in only a few cases reported

Shared Decision Making and Cardioneuroablation Allow Discontinuation of Permanent Pacing in Patients with Vagally Mediated Bradycardia

Journal of Cardiovascular Development and Disease, 2023
Background: Safe discontinuation of pacemaker therapy for vagally mediated bradycardia is a dilemma. The aim of the study was to present the outcomes of a proposed diagnostic and therapeutic process aimed at discontinuing or not restoring pacemaker ...

The association between serotonin transporter availability and the neural correlates of fear bradycardia

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Reduced expression of the serotonin transporter (5-HTT) is associated with susceptibility to stress-related psychopathology, but the underlying mechanisms remain elusive.

Pulselessness After Initiation of Cardiopulmonary Resuscitation for Bradycardia in Hospitalized Children: Prevalence, Predictors of Survival, and Implications for Hospital Profiling.

Circulation, 2019
BACKGROUND Cardiopulmonary resuscitation (CPR) is initiated in hospitalized children with bradycardia and poor perfusion. However, their rate of progression to pulseless cardiac arrest despite CPR, and differences in survival compared with initially ...

Targeting miR-423-5p Reverses Exercise Training–Induced HCN4 Channel Remodeling and Sinus Bradycardia

Circulation Research, 2017
Rationale: Downregulation of the pacemaking ion channel, HCN4 (hyperpolarization-activated cyclic nucleotide gated channel 4), and the corresponding ionic current, If, underlies exercise training–induced sinus bradycardia in rodents.
