Sick sinus syndrome (SSS) is a sinoatrial dysfunction that occurs secondary to hypertension, ar-teriosclerotic heart disease, or rheumatic heart disease. SSS causes arrhythmias with subsequent syncope, transient dizzy spells, light-headedness, seizures, palpitations, angina, or congestive heart failure (CHF). Bacterial endocarditis presents with prolonged fever, signs of neurologic dysfunction, and sudden onset of CHF. Chest pain is an initial symptom in acute pericarditis, along with a triphasic friction rub.
