Normal adult heartbeat is 60-100 beats per minute, if it is more than 100 beats, then the heart is beating too fast, which is called tachycardia in medical terms.
Under normal circumstances, the heartbeat is initiated by the sinus node, the supreme "command" of the pacing and conduction system, so it is called sinus rhythm.
1) Sinus tachycardia
is quite common. As the name suggests, this type of tachycardia is initiated by the sinus node. During an attack, the heart rate is between 100 and 150 beats per minute in adults and up to 200 beats per minute in young children. It is characterized by a gradual onset and disappearance. Sinus tachycardia can be seen in normal people, and common triggering factors include emotional excitement, excessive fatigue, nightmares, drinking alcohol, strong tea and coffee, and heavy smoking. There is no need for special treatment, as long as the triggering factors are eliminated, it will recover on its own.
Sinus tachycardia can also be caused by certain diseases, such as fever, anemia, pregnancy, hyperthyroidism, heart failure, shock, and vegetative nervous system dysfunction, etc., at this time the main cause of the treatment should be targeted, and can be under the guidance of the doctor to choose to take the following medications, such as oxycodone, 10 mg / time, 3 times / day, but asthma, heart failure, hypotension, and pregnant women are prohibited; Valium, 2.5-5 mg / time, 3 times / day. 2.5 - 5 mg / times, 3 times / day; acupuncture points such as Neiguan, Hegu, Shenmen have some effect.
2) Paroxysmal tachycardia
It is not initiated by the sinus node, but by ectopic pacing points (referring to the atria, ventricles, and certain tissues in the junction area between the atria and ventricles).
Based on the location of the ectopic pacing site, paroxysmal tachycardia is divided into three types:
1. Tachycardia caused by an ectopic pacing site in the atria is called atrial tachycardia.
2. Tachycardia caused by an ectopic pacing site in the atrial-ventricular junction region is called atrioventricular junctional tachycardia.
3. Tachycardia caused by an ectopic pacing site in the ventricle is called ventricular tachycardia.
Because atrial and atrioventricular junctional tachycardias are often not easily distinguished on the electrocardiogram, they are collectively referred to as supraventricular tachycardias.
Paroxysmal supraventricular tachycardia can be seen in normal people, but it can also be seen in patients with various heart diseases, hyperthyroidism, and digitalis intoxication. It is characterized by sudden onset and abrupt termination, lasting for several minutes or even hours, accompanied by panic, shortness of breath, dizziness, fear, fatigue, pressure or suffocation in the precordial area, and even heart failure and fainting. The heart rate is 160--250 beats per minute with regular rhythm. Rest should be taken immediately during the attack to eliminate the patient's concerns.
3) Treatment
The use of the following methods of stimulation of the vagus nerve can often quickly stop the seizure:
1. Sudden forceful cough.
2. large mouthfuls of food or water.
3. Tilting the head back or bending the body forward as far as possible.
4. Inhaling y, then holding your breath and exhaling forcefully.
5. Stimulate the pharynx with a tongue depressor or chopstick to cause nausea and vomiting.
Also, acupuncture points such as Neiguan, Tongli and Shenmen are effective.
4) Love Tips
1. When the above treatments are not effective, a doctor should be consulted.
2. Paroxysmal ventricular tachycardia is often seen in severe heart disease and drug intoxication. During the attack, the heart rate is 150-200 beats per minute, often with panic, shortness of breath, pain in the precordial area, dizziness, pallor, sweating and other symptoms, most of the drop in blood pressure, and even heart failure, shock or fainting, and once it evolves into a fatal arrhythmia - ventricular fibrillation, sudden death can occur.
Therefore, the attack should immediately let the patient rest, oxygen, oral valium 5 mg, and quickly send the patient to the hospital for treatment.
