Incidence of Ventricular Fibrillation in Patients With Out-of-Hospital Cardiac Arrest in Japan Survey of Survivors After Out-of-Hospital Cardiac Arrest in Kanto Area (SOS-KANTO)

“…[1][2][3][4]18,20 Common characteristics of fatal arrhythmias in patients with ischemic heart disease are: a ventricular tachyarrhythmia triggered by acute myocardial ischemia in patients with or without preexisting myocardial scarring, or ventricular tachyarrhythmia related to an anatomical substrate without active or clinically obvious myocardial ischemia. 2,20,21 Epidemiologic data indicate that structural coronary arterial abnormalities and their consequences cause 80% of the cases of VF or pulseless VT, 2,20,22 dilated and hypertrophic cardiomyopathies account for the second largest proportion of 10-15% 2,20 and other cardiac disorders, such as primary electrical and genetic ion-channel abnormalities, valvular or congenital heart disease, account for only a small proportion.…”

“…come of VF or pulseless VT and the time interval from collapse to initial recorded electrocardiogram (ECG), the cause of cardiac arrest and whether there are witnesses to the patient's collapse and bystander instituted CPR, 1,5 few data are available on those connections in Japan. Therefore, the present study evaluated the incidence of VF or pulseless VT as the first cardiac rhythm in patients with out-ofhospital cardiac arrest from a cardiac cause in relation to the introduction of public access defibrillation programs in Japan.…”

Communication Strategies and Timeliness of Response to Life Critical Telemetry Alarms

“…[1][2][3][4][5] In a hospital setting, a centralized electrocardiogram (ECG) telemetry monitoring system (TMS) may be employed to facilitate early identification of critical arrhythmias and acute medical decompensation to prevent an emergent episode. [5][6][7][8][9] Over the last 40 years, the intelligence of the monitoring equipment has significantly improved to include arrhythmia identification algorithms, monitoring for myocardial ischemia, assessment of abnormal repolarization (QT interval), artifact reduction, and multilead monitoring capabilities. 10 Therefore, the role of specially trained central telemetry technicians has expanded beyond observing heart rates and basic rhythms to interpreting complex arrhythmias, identifying ischemic ECG changes, and detecting prolonged QT intervals.…”

Removal of CPR Artifacts From the Ventricular Fibrillation ECG by Adaptive Regression on Lagged Reference Signals

“…Digital Object Identifier 10.1109/TBME.2007.902235 [1] in 2001. Almost half of all out-of-hospital cardiac arrest patients suffer from ventricular fibrillation (VF).…”
