No specific set of criteria has been developed for diagnosis of pacemaker syndrome. Most of the signs and symptoms of pacemaker syndrome are nonspecific, and many are prevalent in the elderly population at baseline. In the lab, pacemaker interrogation plays a crucial role in determining if the pacemaker mode had any contribution to symptoms. [5 ...
Idiopathic giant-cell myocarditis (IGCM) is a cardiovascular disease of the muscle of the heart . The condition is rare; [ 2 ] however, it is often fatal and there is no proven cure because of the unknown nature of the disorder.
These include the prominent "Hadley cells" centered over the tropics and the weaker "Ferrell cells" centered over the mid-latitudes. [3] The Hadley cells result from the contrast of insolation between the warm equatorial regions and the cooler subtropical regions. The uneven heating of Earth's surface results in regions of rising and descending ...
Since pacemaker correction of the third-degree block requires full-time pacing of the ventricles, a potential side effect is pacemaker syndrome, and may necessitate the use of a biventricular pacemaker, which has an additional 3rd lead placed in a vein in the left ventricle, providing more coordinated pacing of both ventricles.

SPRINT’s researchers incorporated 9,361 patients over the age of 50 in the United States and Puerto Rico, who were randomly assigned to a systolic blood pressure goal of either less than 120 ...
Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms (arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1] [2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow heart ...
Hoyeraal–Hreidasson syndrome [2] is a very rare multisystem X-linked recessive disorder characterized by excessively short telomeres and is considered a severe form of dyskeratosis congenita. [ 2 ] [ 3 ] Being an X-linked disorder, Hoyeraal–Hreidasson syndrome primarily affects males.
Individuals who have acquired Lev's disease presents signs and symptoms later in life and are often linked to the use of medication, medical conditions, surgical procedures, or environmental factors. In cases of congenital Lev's disease, it is present from birth and is commonly caused by genetic or developmental factors. [ 8 ]
