Repeatability of Sleep Apnea Detection in 48-Hour Holter ECG Monitoring

ANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 3 2010
Barbara Uzna, ska M.D.
Background: There is a significant relationship between obstructive sleep apnea (OSA) and cardiovascular diseases. Reliability of new methods evaluating apnea in Holter ECG monitoring is still the matter of investigators' studies. Methods: In 48-hour Holter ECG monitoring recordings of 63 patients, we assessed repeatability, comparing the results from both sleep periods. Results: We found good repeatability in evaluation of apnea-hypopnea index value. There was moderate agreement in three categories, that is, normal or bordeline or apneic assignment. Assignment to "healthy" (normal and borderline) or apneic subgroup during consecutive sleep periods showed high repeatability. Conclusions: Holter ECG monitoring is a repetitive method of preliminary diagnosis in patients evaluated for sleep apnea syndrome. Ann Noninvasive Electrocardiol 2010;15(3):218,222 [source]

Challenges of Diagnosis of Long-QT Syndrome in Children

We describe the clinical and genetic characteristics of the family, in which the diagnosis of LQT1 had been made. The electrocardiogram (ECG) characteristics of this patient indicated the likelihood of LQTS1. Polymorphic ventricular extrasystolies and episodes of polymorphic non-sustained ventricular tachycardia were confirmed by Holter ECG monitoring. On the exertional electrocardiogram polymorphic ventricular tachycardia (torsade de pointes) was recorded. Direct sequencing of both DNA strands revealed the absence of mutations or polymorphisms in the KCNQ1, HERG, and SCN5A genes. [source]

Sudden Cardiac Death with Left Main Coronary Artery Occlusion in a Patient Whose Presenting ECG Suggested Brugada Syndrome

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 11 2003
TADAYOSHI HATA
This article describes a patient who died suddenly during Holter ECG monitoring. A ventricular premature systole with an extremely short coupling interval of 240 ms was immediately followed by torsades de pointes, soon degenerating into ventricular fibrillation. Retrospective survey of the patient's medical records revealed an incomplete right bundle branch block (iRBBB) configuration with fluctuating saddle back-type ST elevation in leads V1 and V2, these suggesting Brugada syndrome. Autopsy showed complete thrombotic occlusion of the left main coronary artery. (PACE 2003; 26:2175,2177) [source]

Evaluation of Patients with Palpitations: Cardiac Event Recorder Versus 48-hour Holter Monitoring

Objectives: (1) To compare a diagnostic yield of cardiac event recorders with that of 48-hour Holler monitoring, (2) to determine the etiologies of palpitations, and (3) to assess an optimal duration of using an event recorder by a patient. Background: Palpitation is a common symptom which accounts for 16% of total complaints reported by patients in general medical settings. An ambulatory Holter ECG monitoring or an event recorder can be used to establish the cause of palpitations. Methods: (1)The study group consisted of 33 consecutive patients (24 females, 9 males, mean age 50 ± 32 years) with undiagnosed attacks of palpitations, occurring at least once per month. Each patient was randomly allocated to use either an event monitor or 48-hour Holler monitoring. The patient kept the event monitor for 4 weeks. After the first monitor was returned, the patient was given the other device. Results: Holter monitoring determined the etiology of palpitations in 11 (33%) patients, and the event recorder in 21 (64%) patients (P = 0.0138). In the whole study group, the etiology of palpitations was disclosed in 23 (70%) patients. The diagnosis was possible using Holler ECG monitoring in only 2 (9%) patients, whereas the event recorder revealed the underlying mechanism of palpitations in 12 (52%) patients (P = 0.0007). In nine (39%) patients both methods were able to disclose the eliology of palpitations. The findings of 117 recordings obtained using an event recorder during palpitations were atrial fibrillation in 10 (9%), narrow QRS tachycardia in 4 (3%), frequent supraventricular eclopy in 17 (15%), frequent ventricular eclopy in 6 (5%), and episodes of palpitations sinus rhythm were recorded in the remaining 80 (68%). Of patients who experienced episodes of palpitations while using an event recorder, the earliest recording was obtained on the first day of the study, and the latest on the 18 day of using the event recorder. Conclusions: (1) The cardiac event recorders yield more diagnoses than 48-hour Holter monitoring in patients with palpitations occurring at least once per month, (2) in this group of patients the event recorder provided a diagnostic ECG recording during the first 18 days of using the device, and (3) in the majority (57%) of patients a normal sinus rhythm was recorded during episodes of palpitations.
