Bottom Line: The commonest indication for Holter ECG was palpitation followed by syncope in 71 (23%) and 49 (15.8%) of subjects, respectively.The HRV, using standard deviation of averages of normal to normal intervals average (milliseconds), of patients with palpitation, stroke, and diabetes mellitus with autonomic neuropathy were 77.39±62.34, 57.82±37.05, and 55.50±12.71, respectively.Palpitation and syncope were the commonest indications for Holter ECG among our subjects.

ABSTRACT

Background: Facilities for Holter electrocardiography (ECG) monitoring in many Nigerian hospitals are limited. There are few published works in Nigeria on the use of 24-hour Holter ECG in cardiac arrhythmic evaluation of patients with cardiovascular diseases.

Objective: To study the clinical indications, arrhythmic pattern, and heart rate variability (HRV) among subjects referred for 24-hour Holter ECG at our Cardiac Care Unit.

Methods: Three-hundred and ten patients (134 males and 176 females) were studied consecutively over a 48-month period using Schiller type (MT-101) Holter ECG machine.

Results: Out of the 310 patients reviewed, 134 were males (43.2%) and 176 were females (56.8%). The commonest indication for Holter ECG was palpitation followed by syncope in 71 (23%) and 49 (15.8%) of subjects, respectively. Premature ventricular complex and premature atrial complex were the commonest types of arrhythmia in 51.5% and 15% subjects, respectively. Ventricular arrhythmia was more prevalent in dilated cardiomyopathy patients (85.7%). The HRV of subjects with palpitation, stroke, and diabetes mellitus with autonomic neuropathy, using standard deviation of normal to normal intervals average (milliseconds), were 107.32±49.61, 79.15±49.15, and 66.50±15.54, respectively. The HRV, using standard deviation of averages of normal to normal intervals average (milliseconds), of patients with palpitation, stroke, and diabetes mellitus with autonomic neuropathy were 77.39±62.34, 57.82±37.05, and 55.50±12.71, respectively.

Conclusion: Palpitation and syncope were the commonest indications for Holter ECG among our subjects. The commonest arrhythmic patterns were premature ventricular complex and premature atrial complex, with ventricular arrhythmia being more prevalent in dilated cardiomyopathy. There was a reduction in HRV in patients with stroke and diabetic autonomic neuropathy.

Mentions: Premature ventricular complex (PVC) was the commonest type of arrhythmia accounting for 51.5% among patients with arrhythmia, followed by premature atrial complex 15%, as shown in Table 4. The male to female ratio of PVC among the studied patients is 0.9:1.1. Nineteen point six percent of patients <50 years had PVC while 31.2% of patients ≥50 years had PVC. Ventricular arrhythmia was found more prevalent in dilated cardiomyopathy (DCM) patients (85.7%), hypertensive heart failure (HHF) patients (40.1%), stroke patients (36.3%), and patients with palpitation (32.8%). Eighty percent of diabetes mellitus (DM) patients with autonomic neuropathy and 71.4% of hypertensive heart disease (HHD) patients had normal Holter ECG findings. Six (1.9%) out of the studied patients had sustained ventricular tachycardia (VT) (Figure 2), while eleven patients (3.6%) had severe bradycardia (heart rate [HR] <40 beats per minute). Eleven patients (3.6%) had atrial fibrillation (AF) with 45.5% of them being HHF patients. Two point two percent of patients <50 years had AF while 4.1% of patients ≥50 years had AF. One patient (0.3%) had pacemaker tachycardia. Ninety-two (29.7%) patients had significant sinus pauses. Seventy-six (24.5%) patients had multiple ST depression in channel 1.
