- 临床电生理学 临床电生理学
- 自主神经系统功能 自主神经系统功能
背景情况:
- 神经介导性昏迷 (NMS) 是暂时失去意识的常见原因.
- 倾斜表测试 (TTT) 是NMS的标准诊断工具,但需要专门的设备.
- 需要使用替代方法来评估NMS易感性,特别是在资源有限的环境中.
研究的目的:
- 为了研究PR间隔和心率变化参数之间的相关性,作为表交性心律的指标.
- 确定这些参数是否可以预测神经介导 (NMS) 的倾斜表测试 (TTT) 的结果.
主要方法:

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Electrocardiogram
2.1K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
