The morbidity and mortality from heart failure (HF) differ between patients with reduced (< 50%) and with preserved (≥ 50%) left ventricular ejection fraction (LV EF) on account of many factors, including abnormalities detected in the electrocardiogram (ECG).

2025年1月7日 · According to the American Heart Association (ACA) and the European Society for Cardiology (ESC), there are three types of heart failure: HFPEF, HFmrEF and HFREF. This classification is based primarily on the measurement of left ventricular ejection fraction (LVEF).

2023年6月14日 · Common tests for heart failure include an echo, chest X-ray. EKG and more. The American Heart Association explains the common tests for heart failure and the procedures for diagnosing heart failure.

2024年2月16日 · This article explains what an EKG is and how they help doctors detect heart failure. It also outlines the potential for EKGs to detect past symptoms of heart failure and predict future risk.

2022年4月20日 · HF is a complex clinical syndrome identified by presence of current or prior characteristic symptoms, such as dyspnea and fatigue, and evidence of cardiac dysfunction as a cause of these symptoms (eg, abnormal left ventricular [LV] and/or right ventricular [RV] filling and elevated filling pressures) [1-5].

2024年10月8日 · The most common ECG abnormalities are those associated with atrial and ventricular hypertrophy — typically, left-sided changes are seen but there may be signs of biatrial or biventricular hypertrophy; Interventricular conduction …

2017年11月6日 · Several markers detected on the routine 12‐lead ECG are associated with future heart failure events. We examined whether these markers are able to separate the risk of heart failure with reduced ejection fraction (HF r EF) from …

2012年6月15日 · Heart failure is a common clinical syndrome characterized by dyspnea, fatigue, and signs of volume overload, which may include peripheral edema and pulmonary rales. Heart failure has high...

2020年4月27日 · Chronic heart failure: syndrome with reduced cardiac output due to impaired cardiac contraction; symptoms: shortness of breath, fatigue, ankle swelling. Prevalence: 1-2%, increases to 10% in those over 70. Pathophysiology: Stroke volume requires adequate preload, myocardial contractility and decreased afterload. CO = HR x SV.

An electrocardiogram (ECG) is often abnormal in patients with heart failure, although up to 10% of patients may have a normal ECG. Natriuretic peptides are a useful biomarker for heart failure and a negative result can rule out the diagnosis.
