“…Many cardiac arrhythmias may be hard to identify, partly due to their intermittent nature—only 47% of symptomatic arrhythmias are discovered using conventional 24-h Holter monitoring [8]. Some of these arrhythmias become manifest only during or after strenuous physical activity and are occasionally symptoms of potentially life-threatening conditions [9].…”

Background Several wireless ECG devices are commercially available for possible screening, monitoring and diagnosis of rhythms. The field is rapidly expanding, and some devices have demonstrated acceptable qualities. The objective was to evaluate the accuracy, usability and diagnostic capabilities of smartphone ECG in both patients and healthy controls. Methods We used a commercially available smartphone ECG device, connected wirelessly to a tablet, to record a 30-s lead I ECG in 144 subjects—20 of whom repeated the test after vigorous exercise. The subjects included 94 patients under standard calculated 12-lead ECG surveillance; transcripts were obtained shortly after the smartphone ECG was acquired. Results No significant differences were found in the QRS, frequency and QT intervals between the two modalities. Smartphone ECG recordings separated pathologic rhythms (atrial fibrillation (AF)/flutter, atrioventricular block, regular supraventricular rhythm, and pacing) from sinus rhythms with a sensitivity of 0.75 and a specificity of 0.97. The specific diagnosis of AF appeared in 11 patients and was detected with a sensitivity of 1 and a specificity of 0.94. There was a marginal decrease in the interpretability of the smartphone ECG after exercise. Inter- and intraobserver variability was low. Conclusions Smartphone ECG accurately measures most baseline intervals and has acceptable sensitivity and specificity for pathological rhythms, especially for AF. Vigorous activity has a minor influence on the readability of the PR interval. Elderly patients may face challenges in recording a smartphone ECG correctly without assistance. According to our findings, the smartphone ECG would be applicable as a screening device for pathological rhythms.

“…Although Holter monitoring has frequently been used for this purpose, the reported diagnostic yield of Holter monitoring in human patients with unexplained syncope is only about 10%. [4][5][6]10 A recent study evaluating clinical utility of Holter monitoring in dogs with syncope reported a diagnostic yield of 42%. 3 However, when strict criteria for correlating arrhythmias with syncope were used, diagnostic yield of Holter monitoring was only 20%.…”

“…[1][2][3] However, obtaining such a recording is often difficult because of the infrequent, sporadic, and unpredictable nature of the clinical signs. Although continuous ambulatory electrocardiography (Holter monitoring) has become a popular technique for evaluating episodic clinical abnormalities that could potentially be a result of underlying cardiac arrhythmias, [4][5][6][7] typical Holter monitors record the electrocardiogram for only 24 to 48 hours, and patients may not have any episodes of clinical abnormalities during the monitoring period. Consequently, this technique frequently does not provide useful diagnostic data in human [8][9][10][11] and veterinary 3,12 patients with syncope.…”

“…Event monitors (implantable or portable) are indicated for detecting symptoms which occur rarely, but which have significant hemodynamic impairment and prolonged duration and which place the elderly patient's life at risk. 270-274 In cases of effort-induced symptoms, treadmill ET may clarify diagnostic suspicion (chronotropic incompetence or advanced degree of AVB). EPS is indicated for patients with inconclusive 24-h Holter or loop monitor results and unexplained recurrent syncope.…”
