概括
单腔 (SC) 和双腔 (DC) 植入式心脏转移器-除器 (ICD) 区分算法在预防不适当的治疗时具有相似的有效性. 这项研究表明,即使在双腔装置患者中,SC区分也是一种可行的选择.
科学领域:
- 心脏病学
- 生物医学工程
背景情况:
- 现代植入式心脏除器 (ICD) 使用单腔 (SC) 和双腔 (DC) 区分算法来区分心律失常并减少不适当的治疗.
- 虽然被认为具有形态检测的SC算法可以与DC算法竞争,但支持数据很少.
研究的目的:
- 为了比较SC和DC区分算法的有效性来识别恶性心律失常症.
- 评估SC和DC ICD区分策略之间不适当治疗的风险.
主要方法:
- 对来自单一制造商的557名患者的远程监测数据的回顾性分析.
- 根据编程区分算法将患者分为SC (n=124) 和DC (n=433) 组.
- 主要结论是不适当的ICD治疗的发生率;敏感性分析包括具有形态歧视的SC患者.
主要成果:
- 在SC和DC区分组中,不合适的ICD治疗的发生率是可比的 (HR 1. 165;95% CI 0. 393- 3. 448;p=0. 783).
- 对具有形态差异的SC患者的敏感性分析也显示没有显著差异 (HR 1. 809; 95% CI 0. 241 - 13. 577; p=0. 564).
结论:
- 在ICD患者中,单腔区分算法显示与双腔区分算法相比,不适当治疗的风险相似.
- 根据这项远程监测研究, SC 区分是一种合适的替代方案,即使对于可以使用双腔装置的患者也是如此.

Pulse rhythm
925
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Dysrhythmias II: Classification of Tachyarrhythmias
135
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Dysrhythmias V: Evaluating Dysrhythmias
117
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Holter Monitor: 24-Hour Monitoring
259
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
