Electrophysiological abnormalities

Introduction The electrical activity of normal people and patients is different, so it is possible to diagnose certain diseases through electrophysiological examination. The most common electrophysiological abnormalities are prolonged action potentials, and changes in myocardial cell membrane currents such as l-type calcium current, transient outward current, and inward rectification current. The content of electrophysiological examination is to record intracardiac electrical activity during self-heart rhythm or pacing rhythm, and analyze its performance and characteristics for reasoning.

Cause

Heart disease, such as arrhythmia, cardiac hypertrophy, sudden death, etc.

Cardiac electrophysiological examination mainly includes esophageal pacing and intra-arterial placement of electrodes for electrical stimulation. The content of electrophysiological examination is to record intracardiac electrical activity during self-heart rhythm or pacing rhythm, analyze its performance and characteristics for reasoning, make comprehensive judgment, and provide clinicians with a correct diagnosis of arrhythmia, pathogenesis, and treatment options. And even the decisive basis for prognosis and other aspects.

Differential diagnosis

1, adolescent sudden death, a common cause of electrophysiological abnormalities of the heart. Many congenital cardiomyopathy are actually high-risk factors that cause disease, such as sudden changes in myocardial ions, overwork, and strenuous exercise. Serious organ dysfunction can occur, causing the heart to suddenly stop activity and directly cause death.

2. Electrophysiological abnormalities occur in cardiomyocytes. These electrophysiological abnormalities can increase the self-discipline and excitability of cardiomyocytes, resulting in ventricular arrhythmias.

3, cardiac hypertrophy is a response of the heart to mechanical overload and changes in the body's neurohumoral fluid, not only in the changes in the structure of the heart, but also significant changes in electrophysiological properties.
