ICD-10 | Ventricular premature depolarization (I49. 3)
Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles).
Ventricular premature complexes occur when the lower chambers of your heart contract before they should. When this happens, your heartbeat becomes out of sync. You may feel a regular heartbeat, an extra heartbeat, a pause, and then a stronger heartbeat. The extra heartbeat is the ventricular premature complex.
Assign I49. 8 Other specified cardiac arrhythmia for ventricular bigeminy. [Effective 14 August 2009, ICD-10-AM/ACHI/ACS 6th Ed.]
Heart disease or scarring that interferes with the heart's normal electrical impulses can cause PVCs. Certain medications, alcohol, stress, exercise, caffeine or low blood oxygen, which is caused by chronic obstructive pulmonary disease (COPD) or pneumonia, can also trigger them.
If your heart feels out of rhythm or "flutters," especially when you have a lot of anxiety, it could be caused by premature ventricular contractions, or PVCs. They're the most common reason for arrhythmia, or an irregular heart rhythm. Some of the other names for PVCs are: Premature ventricular complexes.
Premature atrial contractions (PAC) result from premature electrical activation originating in the upper chambers (the atria) of your heart. Premature ventricular contractions (PVC) result from premature electrical activation originating in the two lower chambers (the ventricles) of your heart.
Ventricular premature complexes (VPCs), or premature ventricular complexes/contractions (PVCs), are ectopic beats that arise from within the ventricles. They are common and can occur in a wide variety of clinical scenarios and also in a diverse population.
During ventricular contraction, the atria relax (atrial diastole) and receive venous return from both the body and the lungs. Then, in ventricular diastole, the lower chambers relax, allowing initial passive filling of the thick-walled ventricles and emptying of the atria.
When this occurs in a three-beat pattern, doctors call it trigeminy. This pattern can be two normal (sinus) beats and one abnormal one. Another trigeminy pattern is two PVCs with one sinus beat. This rhythm is different from bigeminy, where the heart beats with one sinus beat and one PVC.
Trigeminy is a three-beat tightening or contraction that starts in the ventricles. The extra contractions happen sooner than your next usual heartbeat and disrupt the regular pumping order.
ICD-10-CM Code for Cardiac arrhythmia, unspecified I49. 9.
I49.3 is a billable ICD code used to specify a diagnosis of ventricular premature depolarization. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
A premature ventricular contraction (PVC) — also known as a premature ventricular complex, ventricular premature contraction (or complex or complexes) (VPC), ventricular premature beat (VPB), or ventricular extrasystole (VES) — is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator. The electrical events of the heart detected by the electrocardiogram (ECG) allow a PVC to be easily distinguished from a normal heart beat. Although a PVC can be a sign of decreased oxygenation to the heart muscle, often PVCs are benign and may even be found in otherwise healthy hearts.
A group of cardiac arrhythmias in which the cardiac contractions are not initiated at the sinoatrial node. They include both atrial and ventricular premature beats, and are also known as extra or ectopic heartbeats. Their frequency is increased in heart diseases.
