Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
ACM is a progressive disease. Over time, the right ventricle becomes more involved, leading to right ventricular failure. The right ventricle will fail before there is left ventricular dysfunction. However, by the time the individual has signs of overt right ventricular failure, there will be histological involvement of the left ventricle.
Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachycardia); it is classified as a type of supraventricular tachycardia (SVT).
The HeartWare HVAD could be implanted through limited access without sternotomy, however in 2021 Medtronic discontinued the device. [47] [44] In a small number of cases left ventricular assist devices, combined with drug therapy, have enabled the heart to recover sufficiently for the device to be able to be removed (explanted).
Childhood dementia is very often diagnosed late, misdiagnosed, or not diagnosed at all. [9] A correct diagnosis happens, on average, 2 years or more after symptoms become apparent. Additionally, children affected by childhood dementia are often misdiagnosed with: Autism [16] [9] [17] Developmental or intellectual delay [16] [9] ADHD [9] Others [9]
Premature ventricular contraction usually originates from an area of Ectopic focus. In this illustration ectopic area is near papillary muscles in the left ventricle. Most commonly in healthy hearts PVCs occur near right ventricular outflow tract (RVOT). A premature ventricular contraction on an EKG, marked by the arrow: Specialty: Cardiology
However, ventricular tachycardia and ventricular fibrillation remain the most important causes of sudden death following spontaneous restoration of antegrade flow. [6] Prior to the modern practice of percutaneous coronary intervention for acute coronary syndrome , pharmacologic thrombolysis was more common and accelerated idioventricular ...
Vascular dementia is the second-most-common form of dementia after Alzheimer's disease in older adults. [4] The prevalence of the illness is 1.5% in Western countries and approximately 2.2% in Japan.
