![]() If you have sick sinus syndrome, your sinus node isn’t working properly, causing your heart rate to be too slow (bradycardia), too fast (tachycardia) or irregular. Can your sinuses affect your heart?įrom the sinus node, electrical signals travel across the atria to the ventricles, causing them to contract and pump blood to your lungs and body. If you have fainting, swelling in your leg, shortness of breathseek medical attention right away, Dr. Methods We included 107,838 patients (age, 52.1 15.5 years men, 46.8) who underwent electrocardiography in outpatient clinics or medical checkup (unmatched cohort). However, if symptoms last for long periods of time, are significant or come back time and again, it’s important to seek medical attention. We aimed to elucidate the long-term prognosis of nonspecific intraventricular conduction delay (NIVCD) in patients with structurally normal heart. When should I be worried about an irregular heartbeat?Īn occasional abnormal heartbeat is not cause for serious concern. It gets its name from how it mainly affects the heart’s lower chambers and changes how electrical current travels through them. It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). An ST-elevation myocardial infarction (STEMI) is a type of heart attack that is more serious and has a greater risk of serious complications and death. ![]() What does sinus mean in ECG?Ī sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. However, anxiety might induce electrocardiographic (ECG) changes in normal person with normal heart, as in this documented case. ![]() Premature ventricular contractions is one of the manifestations of sympathetic over activity due to anxiety. ![]()
