Occasionally, the patient having the PAC will find these symptoms bothersome, in which case the doctor may treat the PACs. Sometimes the PACs can indicate heart disease or an increased risk for other cardiac arrhythmias. In this case, the underlying cause is treated. Often a beta blocker will be prescribed for symptomatic PACs. [9]
Ectopic beats are considered normal and are not indicative of cardiac pathology. Ectopic beats often remain undetected and occur as part of minor errors in the heart conduction system. They are rarely indicative of cardiac pathology, although may occur more frequently or be more noticeable in those with existing cardiac abnormalities.
Premature atrial contractions (PACs or APCs) – Normal beats originate in the SA node and extra beats originating from the atria are called PACs. They can be found in normal hearts and be asymptomatic; symptomatic PACs can be treated with beta blockers. PACs, like PVCs, can pair up with normal beats in a pattern called bigeminy.
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
However, until PACS penetration is complete, individual islands of digital imaging not yet connected to a central PACS may exist. These may take the form of a localized, modality-specific network of modalities, workstations and storage (a so-called "mini-PACS"), or may consist of a small cluster of modalities directly connected to reading ...
visualize the arteries and chambers of the heart A catheterization laboratory , commonly referred to as a cath lab , is an examination room in a hospital or clinic with diagnostic imaging equipment used to visualize the arteries of the heart and the chambers of the heart and treat any stenosis or abnormality found.
used to correct abnormal electrical activity of the heart like when terminating a fibrillation: Vascular stents: used to mechanically open up a coronary artery occlusion, generally due to atherosclerosis: Pacemaker: used to correct the hearts rate and rhythm
Yet heart problems often produce no symptoms until very advanced, and many symptoms, such as palpitations and sensations of extra or missing heart beats correlate poorly with relative heart health vs disease. Hence, a history alone is rarely sufficient to diagnose a heart condition.
