Generally, the normal ECG rhythm is also sinus, and the heart rate can exceed or be less than the normal range. Some ECG waveforms have slight changes, but the time is within the normal range, such as sinus arrhythmia. Because there are many influencing factors, it is generally of little practical significance.
Abnormal ECG rhythm can be sinus or non-sinus, the heart rate changes greatly, the time and voltage of ECG exceed the normal standard, or there are obvious abnormalities, and ectopic beats can also be seen.
sinus tachy-cardia
Refers to the adult sinus heart rate exceeding 100 beats/minute. Common causes are fever, anemia, hyperthyroidism, hemorrhage, shock, pain, hypoxia, myocarditis, rheumatic fever, heart failure and so on. It can also be seen after physical activity, emotional excitement, full meal, drinking strong tea and coffee, smoking, drinking, pregnancy and so on. Some drugs such as adrenaline, isoproterenol, ephedrine, atropine and anisodamine can also cause sinus tachycardia.
suggestion
Check the electrocardiogram, check all thyroid functions and rule out hyperthyroidism.
Health education prescription:
If necessary, further dynamic electrocardiogram should be done.
B. Learn to monitor the pulse correctly so as to observe the condition.
C maintain a good mood and mentality; Avoid fatigue, infection, colds and other stimuli.
Quit smoking and limit alcohol, quick strong tea, coffee, etc. And don't overeat at every meal.
E eat more foods rich in dietary fiber to keep the stool unobstructed.
F go to the hospital in time if you have conscious symptoms and use drugs reasonably under the guidance of a doctor.
sinus brady-cardia
Refers to the adult sinus heart rate below 60 beats/min. It can be seen in intracranial hypertension, hypothyroidism, coronary heart disease and acute myocardial infarction. Especially in patients with sick sinus syndrome, this is very dangerous; Physiologically, it can be seen in athletes and the elderly.
Sinus irregularity
It is common in young people, especially when the heart rate is slow or the vagus nerve tension is high (for example, after taking digitalis or morphine).
