Key result
Increased total P-wave duration, negative phase in lead V1, and Macruse index are associated with an increased prevalence of supraventricular rhythm disorders in men with metabolic syndrome.
Why the study?
Are P wave parameters on 24-hour ECG associated with the development of cardiac rhythm disorders in men with metabolic syndrome?

Are P wave parameters on 24-hour ECG associated with the development of cardiac rhythm disorders in men with metabolic syndrome?
Increased P-wave duration, Macruse index, and negative P phase in lead V1 are associated with a higher prevalence of supraventricular rhythm disorders in men with metabolic syndrome.
Answers are grounded in this paper and cite their sources.
P-wave parameters may aid identification of higher-risk men with metabolic syndrome; leaves open prospective prediction of incident arrhythmias.
Aim. To study the parameters of P wave in metabolic syndrome (MS) patients and to evaluate their relation with cardiac rhythm disorders development. Material and methods . Totally, 203 men studied with MS and 16 comparable by age men with arterial hypertension alone. All participants underwent 24-hour electrocardiogram monitoring (ECG), where the P wave length was measured, as Macruse index and length of negative P phase in lead V1. According to the presence of arrhythmia, patients were selected to groups: no arrhythmia, ventricular extrasistoly, supraventricular extrasystoly and atrial fibrillation. Results. In supraventricular extrasistoly group and in paroxysmal atrial fibrillation group all parameters of atrial ECG were significantly increased and were higher than the same parameters in control group, as in patients with ventricular extrasistoly or no arrhythmia. Conclusion. The increase of total P-wave duration and of negative phase in lead V1, as well as Macruse index is associated with increased prevalence of supraventricular rhythm disorders in MS.

Dzhishambaev et al. (2016) conducted an observational in Metabolic syndrome and cardiac arrhythmias (n=219). P wave parameters (total P-wave duration, negative phase in V1, Macruse index) vs. Arterial hypertension alone or no arrhythmia was evaluated on Parameters of atrial ECG (P wave length, Macruse index, length of negative P phase in lead V1). Increased total P-wave duration, negative phase in lead V1, and Macruse index are associated with an increased prevalence of supraventricular rhythm disorders in men with metabolic syndrome.
