What Are Tachycardia Causes?

Tachycardia means a heart rate of more than 100 beats per minute. Tachycardia is divided into two types: physiological and pathological. Accelerating heart rhythm during running, drinking, heavy physical exertion, and emotional agitation is physiological tachycardia; if high fever, anemia, hyperthyroidism, bleeding, pain, hypoxia, heart failure, and cardiomyopathy cause tachycardia, it is called pathological cardiac Overspeed. Symptoms such as palpitations, chest pain, dizziness, dizziness, coma, or semi-coma may occur if the heartbeat is too fast to maintain effective blood circulation. When tachycardia occurs, the heart rhythm may be regular or irregular. Urgent patients are advised to cough, take a deep breath, stimulate the pharynx, and press the eyeballs to relieve certain tachycardia; drugs can temporarily "terminate" the attack; radiofrequency ablation can cure some tachycardia.

Common causes

Pathological tachycardia is common in fever, anemia, hyperthyroidism, bleeding, pain, hypoxia, heart failure, and cardiomyopathy.

Causes of tachycardia and common diseases

Ventricular tachycardia

Rapid heartbeats originate in the ventricles and may affect the heart to pump enough blood into the brain and other vital organs.

2. Atrial tachycardia

Referred to as room rate. Atrial tachycardia often occurs in patients with severe organic heart disease and digitalis poisoning, and the episodes are brief or last several months. When the atrioventricular conduction ratio changes, the auscultation rhythm is not constant, and the first heart sound intensity changes.

Pathological tachycardia is common in diseases such as high fever, anemia, hyperthyroidism, bleeding, pain, hypoxia, heart failure, and cardiomyopathy.

Tachycardia differential diagnosis

Differentiation from physiological tachycardia. Physical tachycardia often speeds up during running, drinking, heavy physical exertion, and emotional agitation.

Tachycardia

The examination relies mainly on the electrocardiogram.

Tachycardia treatment principles

Emergency treatment

(1) Ask the patient to cough loudly.

(2) Ask the patient to take a deep breath, hold their breath, and then make a forced exhalation.

(3) Instruct patients to use their fingers to stimulate the throat, causing nausea and vomiting.

(4) The patient is instructed to close his eyes and look down, using his fingers to press the upper part of the eyeball under the orbit, and then press the right eye first. At the same time, take a pulse to count the heart rate. Once the tachycardia stops, stop the compression immediately. But do not use too much force, 10 minutes each time, the compression of one side is not effective, then change the opposite side, do not press on both sides at the same time. Glaucoma and high myopia are contraindicated.

2. Drug treatment

Cardiac rhythm, verapamil, etc. can stop some tachycardia attacks, but they cannot be cured, bolus drugs have certain risks, and long-term medication is not recommended to prevent recurrence of tachycardia.

3. Radiofrequency ablation

It can cure tachycardia and eliminate the need for antiarrhythmic drugs after operation; the patient has no pain and the operation method is simple. It is characterized by small trauma, fast recovery and high cure rate.
