Under normal circumstances, the heart beat is pacing and conduction system of the highest "Command" - Sinus launched, so called sinus rhythm. The normal adult heart beat per minute, 60 ~ 100 times, if more than 100 times, is the heartbeat too fast, medicine called tachycardia. There are many reasons causing tachycardia, tachycardia occurs when the family members, we can take what contingency measures for the treatment of late to win time?
Sinus tachycardia is common. As the name suggests, such a tachycardia is initiated by the sinoatrial node. Attack, adult heart rate per minute at 100 ~ 150 times between early childhood up to 200 times per minute. Its characteristics are gradually occurred gradually disappear. Sinus tachycardia can be found in normal, common predisposing factors are emotional fatigue, alcohol consumption, drinking tea, drinking coffee and smoking a lot. Generally no special treatment, as long as the elimination of predisposing factors will be self-healing. Sinus tachycardia can also be caused by certain diseases, such as fever, anemia, pregnancy, hyperthyroidism, heart failure, shock and autonomic dysfunction and so on. This should be cause for treatment, and doctors serving under the guidance of the election of the following drugs: propranolol, each 10 mg 3 times a day, but for asthma, heart failure, low blood pressure patients and pregnant women, disabled; stability, each 2.5 ~ 5 mg 3 times a day.
Paroxysmal tachycardia was not initiated by the sinoatrial node, but by the ectopic pacemaker (referring to the atrial and ventricular and atrial-ventricular junction of certain organizations) launched. According to the site where the ectopic pacemaker, paroxysmal tachycardia again be divided into three kinds: from atrial ectopic pacemaker is called tachycardia caused by atrial tachycardia; from the atrium and ventricle at the junction of ectopic pacemaker area called the atrioventricular junctional tachycardia induced tachycardia; from ventricular tachycardia caused by ectopic pacemaker is called ventricular tachycardia. As the atrial and atrioventricular junctional tachycardia often difficult to distinguish in the electrocardiogram, so put them collectively referred to as supraventricular tachycardia.
Paroxysmal supraventricular tachycardia can be found in normal people, but also can be found in a variety of heart disease, hyperthyroidism, patients with digitalis poisoning. Characterized by sudden onset, an abrupt end, more than several minutes or even hours, and accompanied by palpitation, shortness of breath, dizziness, fear, fatigue, precordial, or choking feeling intimidated and even heart failure, syncope and so on. Heart rate 160 ~ 250 times per minute, rhythm rule. If found to attack the family this has happened should be persuaded to rest immediately and eliminate concerns. Can take the following methods to stimulate the vagus nerve in patients often can quickly make seizures stop:
1. To enable patients to force a sudden cough.
2. To enable patients to eat or drink big mouth.
3. To enable patients to the head or body before bending their heads off.
4. Deep inspiration breath-hold, and then deep-breath action masterpiece.
5. With the spatula or chopsticks to stimulate the patients throat, causing nausea and vomiting.
The deal is a contingency measure, after which patients should also be taken to the hospital to conduct the necessary checks, a clear cause, symptomatic treatment.
Paroxysmal ventricular tachycardia are also common in severe heart disease and drug toxicity. Onset heart rate of 150 ~ 200 times / min, often palpitation, shortness of breath, chest pain, dizziness, pale, sweating and other symptoms, blood pressure, the majority of decline or even heart failure, shock or syncope, once turned into a deadly arrhythmia - ventricular fibrillation, sudden death can occur. Therefore, the attack should be immediately to enable patients to rest, oxygen, oral and stability of 5 mg, and speed the patient sent to hospital for treatment.
