まとめ
内心回転は,心房細動 (AF) の治療において,外心回転よりも効果的です. 両方の方法はAFの再発率が類似しており,外部の方法が失敗すると,内心循環がより安全な選択肢である.
科学分野:
- 心臓病学 心臓病学
- 電気生理学 電気生理学
- 医療機器 医療機器について
背景:
- 心房細動 (AF) の管理には,しばしば心臓転換が伴う.
- 外部心臓転換と比較した内部心臓転換の有効性は,依然として調査中です.
- 以前の研究では,AF変換に対する内部ショックの潜在的な利点が示唆されています.
研究 の 目的:
- 慢性AF患者の内部対外心転移の有効性と安全性を前向きに比較する.

- 心臓転換後,シヌスリズムを維持するアミオダロンの役割を評価する.
主な方法:
- 慢性AFの112人の患者を対象としたランダム化研究.
- 患者は,心房電極カテーテルを介して,外部の心転移 (300-360 J) または内部の心転移 (200-300 J) を受けました.
- すべての患者は,低用量のアミオダロンで心臓転換前と後の治療を受け,1年間の追跡調査を行った.
主要な成果:
- 内部心臓転換は,外部心臓転換 (67%) (p=0.002) と比較して,有意に高い有効性 (91%) を示した.
- 体重は,心臓転換の成功に関連する唯一の変数でした.
- AF再発率は,グループごとに似ていた; 37%が1年後に副鼻腔リズムを維持した. 合併症は最小限でした.
結論:
- 慢性AFの患者で副鼻腔リズムを回復するために,内心循環は外心循環よりも優れています.

Pulse rhythm
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 muscle...

Factors Influencing Heart Rate
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Pathophysiology of Cardiac Performance
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
Disturbances in Heart Rhythm
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
