Wenxin Keli
Primary Function: Manages cardiac arrhythmias, particularly premature beats (ectopic beats) and palpitations. Its main action is to stabilize the heart's electrical activity.
Key Components: Dangshen (Codonopsis), Danshen (Salvia), and others.
Clinical Application: Used for symptomatic relief of palpitations, chest tightness, and irregular heartbeats often diagnosed as ventricular or supraventricular premature beats. It is commonly used for arrhythmias potentially related to conditions like coronary heart disease or viral myocarditis.
Shensong Yangxin Capsule
Primary Function: Treats both tachyarrhythmias (fast rhythms) and bradyarrhythmias (slow rhythms) by regulating the heart rate. It aims to "nourish the heart" and improve the underlying condition.
Key Components: Renshen (Ginseng), Maidong (Ophiopogon), and Suanzaoren (Ziziphus seed).
Clinical Application: Used for various arrhythmias, including frequent premature beats, paroxysmal atrial fibrillation, or even mild sinus bradycardia. It addresses accompanying symptoms like palpitations, shortness of breath, fatigue, and insomnia.
Qili Qiangxin Capsule
Primary Function: Treats heart failure. It focuses on strengthening heart contraction, promoting diuresis (fluid removal), and reducing cardiac load.
Key Components: Huangqi (Astragalus), Fuzi (Aconite), and Zexie (Alisma).
Clinical Application: Used for patients with chronic heart failure showing symptoms like dyspnea (especially on exertion), fatigue, leg edema, and abdominal distension. It is often an adjunct therapy to improve cardiac function and quality of life.
Summary of Key Differences:
| Feature | Wenxin Keli | Shensong Yangxin Capsule | Qili Qiangxin Capsule |
|---|---|---|---|
| Core Target | Arrhythmias (Irregular beats) | Arrhythmias (Both fast & slow) | Heart Failure (Weak pumping) |
| Primary Action | Stabilizes electrical impulses | Regulates heart rate & nourishes | Strengthens contraction, diuresis |
| Main Symptoms Addressed | Palpitations, chest tightness | Palpitations, fatigue, insomnia | Shortness of breath, edema, fatigue |
In practice:
For palpitations/irregular heartbeat without severe weakness, Wenxin Keli is often chosen.
For more complex arrhythmias with fatigue or sleep issues, Shensong capsule is typically preferred.
For heart failure symptoms like breathlessness and swelling, Qili Qiangxin capsule is the primary choice.
