Is there any influence of elevated diastolic blood pressure on ventricular arrhythmias in hypertensive patients with left ventricular hypertrophy?

CROATICAObjective: To investigate the prevalence of ventricular arrhythmias in a patient with isolated systolic hypertension (ISHT) and left ventricular hypertrophy (LVH) in comparison to patients with systolic and diastolic hypertension and LVH.Patients and Methods: 192 (87 men) patients with essential hypertension and LVH were divided into two groups: 98 patients with ISHT and 94 patients with systolic and diastolic hypertension.After discontinuing all medications for a period of 48 hours, the blood pressure was measured, electrocardiography, echocardiography, Holter monitoring and bicycle ergometry were performed.The number of ventricular arrhythmias was recorded.Antihypertensive drugs and the duration of previous treatment were taken into consideration.Results: Isolated systolic hypertension (systolic blood pressure >140 mmHg and diastolic blood pressure <90 mmHg)
