Sinus Arrhythmia: Heart Rhythm Disorder Often Benign, Diagnosed via EKG

Sinus arrhythmia, a heart rhythm disorder where the heart beats too fast or slow, sometimes in sync with breathing, can occur alone or alongside other heart conditions like sinus tachycardia or bradycardia. An electrocardiogram (EKG or ECG) is the primary diagnostic tool.

Sinus arrhythmia can be benign, with no symptoms, or cause issues like heart palpitations, lightheadedness, or shortness of breath. It's often discovered incidentally during routine check-ups. Diagnosis involves an EKG, medical history, physical examination, and laboratory tests to rule out underlying conditions.

Respiratory sinus arrhythmia, a common form, occurs when the heartbeat changes with inhalation and exhalation. The prognosis is generally good, with most patients living normal, healthy lives. Treatment is usually not necessary, as it's considered a benign condition. However, if it occurs with another heart condition, treating the original condition may help stop the arrhythmia. For instance, sinus arrhythmia can occur with sinus bradycardia, causing lengthy pauses between beats.

Sinus arrhythmia, a heart rhythm disorder, can be benign or cause mild symptoms. Diagnosis involves an EKG, and treatment is usually not required. However, if it occurs with another heart condition, addressing that condition may help resolve the arrhythmia. The prognosis is generally good, with most patients living normal, healthy lives.
