Hypertension and Arrhythmias

20 Aug Hypertension and Arrhythmias

Introduction

• Hypertension is one of the earliest recorded medical conditions (2.600BC)
• Consequences of hypertension will soon be the leading global cause of death
• The risk of death increases with increasing SBP
• On one hand is a risk factor for the development of coronary artery disease, and on the other hand for the incidence of ventricular arrhythmias or even cardiac death.

Arrhythmogenic Mechanisms in Hypertension

• Duration of the action potential is increased
• The plateau phase of the action potential is more labile than non-LVH
• Disorders of the cytosolic calcium concentrations
• The normal regional differences of action potential duration are reversed
• Reentry seems to be directly linked with fibrosis
• Link of LV wall stress and arrhythmias
• The HRV is decreased
• Electrolyte imbalance such as disorders of calcium and potassium channels
