まとめ
心拍の臨床検査は,しばしば心拍不全を排除するのに不十分である. 再発性心拍の患者における不律を正確に診断するために,長期の心電図モニタリングは一般的に必要である.
科学分野:
- 心臓病学 心臓病学
- 診断の精度 診断の精度
- クリニカル・メディシン 臨床医学
背景:
- パルピテーションは,一般医に提示する一般的な患者の苦情です.
- 良性原因と重大な心律失調の区別は難しいかもしれません.
- 臨床検査は診断のヒントを提供しますが,慎重に解釈する必要があります.
研究 の 目的:
- 患者の病歴,身体検査,心臓検査の診断の正確性を体系的に検討し,心臓の鼓動を感じる患者の心律異常を特定する.
- 臨床的特徴の信頼性を評価し,有意な心律不全の診断または排除を図る.
主な方法:
- MEDLINEとEMBASEのデータベースの包括的な文献検索は,1950年から2009年の間に出版された英語の記事のために行われました.
- 臨床的特徴と診断検査を心律不良の基準基準と比較した研究が選択されました.
- 精度分析のために7つの研究,診断結果分析のために16の研究が含まれており,データは抽出され,品質は複数のレビュー者によって評価されました.
主要な成果:
- 心臓病の病歴,睡眠や仕事中の鼓動,首の脈動は,心律失調の可能性をわずかに高めます.
- パニック障害の既往歴や短期間の心拍が不律症の可能性を低下させる.
- 首の定期的な急速な鼓動の感覚は,心房節回転性心拍動脈を強く示唆しますが,その欠如は,それを排除しません. ループモニターは,心拍不全の検出において,最も高い診断率 (34%-84%) を提供します.
結論:
- 特定の首の感覚は,心房小節回転性心拍動脈のような特定の心律不全を示唆しますが,臨床検査だけでは,ほとんどの患者で重大な心律不全を排除するには不十分です.
- 繰り返し発作する心拍は,正確な診断のために,症状とリズムが相関する長期の心電図モニタリングを必要とします.
- 心電図モニタリングの診断成果は,モニタリング中の方法,期間,および症状の発生によって異なります.

Dysrhythmias V: Evaluating Dysrhythmias
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...
Mechanism of Cardiac Arrhythmias
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.
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.

Dysrhythmias II: Classification of Tachyarrhythmias
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...
ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
Dysrhythmias VII: Nursing Management of Dysrhythmias
Nursing management of dysrhythmias involves the following:AssessmentSubjective Assessment:The initial step involves gathering patient-reported symptoms such as dizziness, palpitations, and chest discomfort. It is crucial to collect a detailed history, including previous heart conditions, current medication use, and lifestyle factors like caffeine and alcohol consumption.Objective Assessment:This involves observing clinical signs such as jugular venous distention, cool and pale skin, and...
