Doctors who carried out the player's autopsy referred to a"cardiac arrest without a visible explanation, in all likelihood due to a bradyarrhythmia
(slow heart rate)", Corriere dello Sport and Tuttosport reported.
The first sign of CHB, such as persistent fetal bradyarrhythmia
, is usually noted between 18th and 24th gestational weeks (GWs).
The incidence of coronary artery disease in patients with symptomatic bradyarrhythmia
Prevention and management of AV blocks and bradyarrhythmia
are very important, because they cause AV dyssynchrony leading to loss of atrial contribution to ventricular filling further jeopardising already decreased cardiac output.
In CCB overdose, cardiovascular collapse, heart block, bradyarrhythmia
and hypotension, hyperglycemia, lactic acidosis, seizures, coma, and non-cardiogenic pulmonary edema and intestinal ischemia may occur (1,3, 9).
Implantable cardiac electronic devices (ICEDs) include pacemakers for bradyarrhythmia
treatment, implantable cardioverter defibrillators (ICDs) for tachyarrhythmia management, and cardiac resynchronization therapy (CRT) devices for systolic dysfunction with conduction delays1.
Participants were excluded from the current analysis for the following reasons: inadequate urine sample volume for metals assays (n = 465); bradyarrhythmia
(heart rate < 40 beats/min) or tachyarrhythmia (heart rate > 100 beats/min) (n = 348), consistent with a previous study (Magari et al.

Two hours after the second dose, she developed a junctional bradyarrhythmia
with the heart rate slowing from 101 to 34 beats/minute and hyperkalaemia up to 6.
It may also manifest in the form of tachyarrhythmia, bradyarrhythmia
, heart failure, thromboembolism or sudden death.
The possible causes of tachyarrhythmia and bradyarrhythmia
following the Fontan procedure may include damage to the sinoatrial (SA) node or the artery, extensive atrial suture lines and incisions, and exposure of the atrial myocardium to prolonged high pressure.
On the tenth post-operative day, she became suddenly unresponsive due to a bradyarrhythmia
that progressed to asystole.
