In cardiology, PNC refers to "premature nodal contraction," which is an abnormal heartbeat originating from the heart's atrioventricular (AV) node. This condition typically results in an early heartbeat that may disrupt the normal rhythm of the heart. While premature nodal contractions can be benign, they may also indicate underlying heart issues, warranting further evaluation. Proper diagnosis and management depend on the patient's overall health and symptoms.
