Background: One disadvantage of current loop recorders is the long interval between recording an electrocardiogram (ECG), establishing a diagnosis, and taking appropriate medical measures. The Cardio R loop recorder transmits cardiac recordings by cellular communication at the push of a button. Users can concomitantly relay symptoms, thereby providing a symptom/cardio-rhythm correlation., Hypothesis: The Cardio R is capable of early detection of cardio-electrical events that could account for patients' symptoms., Methods: This observational study was designed to evaluate patients who were referred from community physicians/cardiologists for evaluation of various cardiac symptoms that were not observed by regular office ECGs or traditional 24-hour Holter cardiac monitoring. Transmitted recordings were instantly displayed on a monitor for immediate diagnosis by the on-duty medical team at SHL-Telemedicine's call center. Abnormal tracings, especially when accompanied by symptoms selected from the prepared list, enabled the staff to instruct the subscriber, notify their physician, and/or dispatch a mobile intensive care unit to the scene., Results: Between January 2009 and August 2010, there were 17 622 ECG transmissions received from 604 patients (age range, 10-95 years) who completed a 1-month trial with the Cardio R device. Palpitation, presyncope, and chest pain were the leading complaints. A disturbance in rhythm that could account for symptoms occurred during recording in 49% cases and was displayed within 7 minutes in 93% of them. No longer than 2 days elapsed from recording onset to diagnosis., Conclusions: The Cardio R device enables prompt ECG confirmation/exclusion of a probable arrhythmic cause of symptoms, enabling rapid intervention for cardiac-relevant complaints., (© 2011 Wiley Periodicals, Inc.)

"SHL" Telemedicine (established 1987 in Israel) provides professional care to subscribers who use cardiobeepers and contact its medical call center via telecommunication networks. The extended 6-month Acute Coronary Syndrome Israel Survey (ACSIS) 2004 involved all 26 intensive cardiac care units in Israeli hospitals. We compared the 1-year survival rates of the "SHL" Telemedicine subscribers and ACSIS participants who survived hospitalization after sustaining an acute myocardial infarction. The myocardial infarction data for the ACSIS cohort (3,899 patients) and the SHL Telemedicine cohort (699 subscribers) were provided for this study by the ACSIS executive and SHL's files, respectively. One-year mortality was ascertained by telephone contacts with patients or their relatives. Mortality at 1 year was 4.4% for the "SHL" patients and 9.7% for the ACSIS patients (p < 0.0001). The "SHL" cohort was significantly older (p < 0.0001) than the ACSIS cohort (mean age [+/-SD] 69 +/- 11 versus 63 +/- 13 years), had significantly more past myocardial infarctions (p < 0.001), more past strokes (p < 0.0032), more heart failure (p < 0.0001), more hypertension (p = 0.002), and more hyperlipidemia (p < 0.0001). Gender distribution and diabetes status were similar for both groups. In spite of having more risk factors than the ACSIS subjects, the "SHL" Telemedicine subscribers had significantly higher survival rates at 1 year compared to the ACSIS patients, whose outcome is consistent with that of the Western world. Availability of medical call centers in the out-of-hospital setting for patients with suspected cardiac symptoms improves their motivation to seek timely and appropriate medical assistance.

Objectives: The only large-scale report (1988) by the Israeli national ambulance service Magen David Adom (MDA) on the outcome of cardiac arrest victims who underwent cardiopulmonary resuscitation (CPR) by paramedics called for more frequent and more promptly initiated CPR and shorter time to arrival of paramedic care to improve survival. We report the 1987-2007 experience of resuscitation of out-of-hospital cardiac arrest victims who were 'SHL'-Telemedicine subscribers and who underwent CPR by SHL-Telemedicine mobile intensive care units (MICUs) personnel or under their instructions., Methods: 'SHL's records of MICU reports and specifics of CPR maneuvers and outcome of resuscitated patients, as recorded by its MICU physicians, were analyzed to determine whether the system enhanced survival., Results: A total of 1810 'SHL'-Telemedicine subscribers (mean age 76+/-12 years [16-104], 67% males) were resuscitated after cardiac arrest, 597 (33%) were hospitalized and 279 (15.4%) were discharged alive. Factors associated with successful resuscitation included witnessed collapse and documented ventricular fibrillation upon MICU arrival. A history of diabetes, hyperlipidemia, stroke or advanced age adversely affected the outcome. Time from collapse to CPR initiation and duration of CPR correlated significantly with survival. Laymen instructed telephonically by the 'SHL'-Telemedicine center performed CPR on 121 patients: 13 (10%) survived to hospital discharge., Conclusions: 'SHL'-Telemedicine's policy of bi-monthly contact with its subscribers led to heightened awareness of warning signs and need for rapid summoning of medical assistance in the setting of out-of-hospital sudden cardiac arrest.
