Background:
The current status of wearable cardiovascular defibrillators (WCD) use in Japan is unclear.
Methods:
Using a nationwide claims database of Japan, we assessed characteristics of patients using WCD and factors influencing subsequent implantable cardioverter-defibrillator (ICD) implantation.
Results:
In 1049 cases, those with prior cardiopulmonary arrest (CPA) or ventricular arrhythmia, cardiomyopathy, or device-related issues were more likely to require permanent ICDs, whereas females were less likely.
Conclusions:
Prior CPA or fatal arrhythmia, underlying cardiomyopathy, or device-related issues were associated with future permanent ICD implantation. These findings offer insights into the current status of WCD use in Japan.

01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
