Oct 31, 2023 · Sinus rhythm is the pattern of electrical pulses from your sinus node, your heart’s pacemaker. Learn about normal sinus rhythm, sinus arrhythmia, sick sinus syndrome, and how they relate to atrial fibrillation.
Schematic representation of normal sinus rhythm showing standard wave, segments, and intervals. A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. It is necessary, but not sufficient, for normal electrical activity within the heart.
Mar 21, 2022 · Sinus arrhythmia is a normal variation of heart rhythm that occurs with breathing. Learn about the types, diagnosis and outlook of this condition from Cleveland Clinic.
May 13, 2024 · Sinus rhythm is the normal pattern of electrical impulses that control the heartbeat. Learn about sinus arrhythmia, bradycardia, tachycardia, and how to treat abnormal sinus rhythms.
Mar 11, 2021 · Learn the features and examples of normal sinus rhythm (NSR), the default heart rhythm with regular, narrow-complex beats. Find out how to distinguish NSR from sinus arrhythmia and sinus bradycardia.
Sinus rhythm is the normal rhythm of the heart with a constant P-wave preceding every QRS complex. Learn how to identify sinus rhythm on the ECG and how to calculate the heart rate manually.
Aug 16, 2022 · Sinus rhythm is the normal, healthy pattern of your heart beating. Learn how an ECG can measure your sinus rhythm and what arrhythmias can affect it, such as AFib, tachycardia, and bradycardia.
