Frequent premature ventricular contractions.
Premature ventricular contractions (PVCs) are considered normal in many circumstances but can act as markers to other cardiac disease such as cardiomyopathy and ischemic heart disease. This case is presented to illustrate frequent PVCs as a marker for serious heart disease.

متن کاملFrequent Premature Ventricular Contractions and Cardiomyopathy, Chicken and Egg situation.
Premature ventricular contractions (PVCs) are usually regarded as benign in the absence of structural heart disease. However, frequent PVCs can lead to depressed LV function, called PVC-induced cardiomyopathy and can be reversible after suppression of PVCs. On the other hand, PVCs can be a part of underlying structural heart disease and may be linked to increased risk of sudden death. In this w...
متن کاملHypoparathyroidism--a cause of reversible dilated cardiomyopathy.
Hypoparathyroidism is associated with chronic hypocalcaemia which can have a variety of manifestations including cardiovascular changes. We describe here a case of primary hypoparathyroidism associated with systolic dysfunction of left ventricle presenting as a dilated cardiomyopathy in addition to other manifestations.
متن کاملHow to find frequent patterns?
An improved version of DF , the depth first implementation of Apriori as devised in [7], is presented. Given a database of (e.g., supermarket) transactions, the DF algorithm builds a so-called trie that contains all frequent itemsets, i.e., all itemsets that are contained in at least minsup transactions with minsup a given threshold value. In the trie, there is a one-to-one correspondence betwe...
