“…palpitations, dizziness) if the 24-h Holter ECG is inconspicuous. 8,9 Despite their promise, these systems have not been able to fully establish themselves in clinical practice. In addition to the substantial weight of a loop recorder, it was not possible for the recorder to automatically detect atrial fibrillation or to transmit the ECG via telephone within a short period of time.…”

In order to test a newly developed algorithm for detecting atrial fibrillation in clinical practice, we carried out parallel recordings using a conventional 24-h electrocardiogram (ECG) monitor and telemonitoring with an external loop recorder. Recordings were made in 24 patients with persistent atrial fibrillation and in another 24 patients with sinus rhythm. Atrial fibrillation was detected immediately in 23 of 24 patients with persistent atrial fibrillation and 20 min after fitting the single-channel loop recorder in the 24th patient (sensitivity 100%). On average, 3.1 false positives (i.e. detection of an episode, including the end or beginning of atrial fibrillation) were transmitted per patient. The sensitivity of the algorithms for automatically detecting bradycardiac and tachycardiac atrial fibrillation was also high. In 12 of 24 patients with sinus rhythm, false-positive tele-ECGs were transmitted. These were caused by supraventricular or ventricular extrasystoles and by sinus arrhythmias or sinoatrial (SA) blocks. The external loop recorder was very effective at detecting paroxysmal atrial fibrillation. Possible indications for the clinical use of this recorder include, in addition to diagnosis, monitoring patients for atrial fibrillation recurrence after cardioversion or catheter ablation.

Palpitation is non-specific and represents one of the most common symptoms in general medical settings.Discerning cardiac from noncardiac causes is important. A 24-hour ambulatory electrocardiography (Holter) monitor is usually used. This is a retrospective cross-sectional review including all patients presented with palpitation and had Holter monitoring performed in a regional primary care clinic of Hong Kong during the year 2010 to 2014. Clinical information and Holter outcomes were retrieved and analyzed to examine Holter monitoring defined significant cardiac arrhythmia and assess the predictive patient characteristics associated with significant cardiac arrhythmia. Holter monitoring were arranged for 89 (31.9%) male and 190 (68.1%) female patients. 163 (58.4%) patients had associated chronic comorbidity, including 38.0% had hypertension. 109 (39.1%) Holter monitoring showed significant cardiac arrhythmia, including prolong QT interval (11.1%), frequent supraventricular/ventricular ectopics (9.0%) and supraventricular/ventricular ectopics in bigeminy or trigeminy (5.0%). Patients who were smokers, or with concomitant ischaemic heart disease were more likely to have significant cardiac arrhythmia (P < 0.05). 39.1% of Holter monitoring for patients presented with palpitation in the primary care setting have significant cardiac arrhythmia, which need referral to medical specialist for further management.

Rarely and transient occurring arrhythmia, palpitation, dizziness, syncopes and chest pain frequently cause symptoms and complaints to patients with congenital cardiac defects. The reliable identification of their pathogenesis is often difficult. The study presented here demonstrates the impact of an event recorder for enlightening sporadically occurring complaints and symptoms. Fifty patients (age between 11 and 70 years, median 27 years) were examined with an event recorder (King of Hearts Express, Instromedix, Hillsboro, USA). The patients were referred to an outpatient clinic for congenital cardiac defects in order to clarify unexplained arrhythmia, palpitations, dizziness, or syncope. Included were patients above 10 years of age. Previous cardiac studies (including ECG, exercise-ECG, Holter-Monitoring) were non-diagnostic in all. Altogether 227 ECGs had been recorded. 95% of them were of diagnostic quality. The event recorder afforded ambulatory monitoring and the median duration of monitoring was 22.5 days. The average number of registered events was 4.5 +/- 3.8. In 24% of the patients (n = 12) diagnostic and/or therapeutical consequences resulted: electrophysiological examination (n = 5), drug treatment (n = 4) and pacemaker implantation (n = 3). The event recorder is an important and highly effective tool in diagnosing sporadical transient symptoms and complaints, especially arrhythmias.
