  2. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    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 ...

  3. Wandering atrial pacemaker - Wikipedia

    en.wikipedia.org/wiki/Wandering_atrial_pacemaker

    Wandering atrial pacemaker may be seen in young, healthy individuals as well as in the elderly and those with lung disease. [2] The cause of wandering atrial pacemaker is unclear. Increased tone from the vagus nerve may factor into the rhythm appearing in young, healthy individuals who exercise. The vagus nerve is a part of the parasympathetic ...

  4. Ectopic pacemaker - Wikipedia

    en.wikipedia.org/wiki/Ectopic_pacemaker

    An ectopic pacemaker, also known as ectopic focus or ectopic foci, is an excitable group of cells that causes a premature heart beat outside the normally functioning SA node of the heart. It is thus a cardiac pacemaker that is ectopic , producing an ectopic beat .

  5. Postpericardiotomy syndrome - Wikipedia

    en.wikipedia.org/wiki/Postpericardiotomy_syndrome

    The typical signs of post-pericardiotomy syndrome include fever, pleuritis (with possible pleural effusion), pericarditis (with possible pericardial effusion), occasional but rare pulmonary infiltrates, and fatigue. [1] [2] Cough, pleuritic or retrosternal chest pain, joint pain and decreased oxygen saturation can also be seen in some cases. [1]

  6. Cardiomegaly - Wikipedia

    en.wikipedia.org/wiki/Cardiomegaly

    Pacemaker: Coordinates contractions between ventricles. In people at risk of arrhythmias, drug therapy or an implantable cardioverter-defibrillator (ICD). ICDs: Small devices implanted in the chest to monitor heart rhythm and deliver electrical shocks to control abnormal heartbeats. The devices can also work as pacemakers.

  7. Pacemaker - Wikipedia

    en.wikipedia.org/wiki/Pacemaker

    A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .

  8. Sinus node dysfunction - Wikipedia

    en.wikipedia.org/wiki/Sinus_node_dysfunction

    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 ...

  9. Mitral regurgitation - Wikipedia

    en.wikipedia.org/wiki/Mitral_regurgitation

    It is one of the two most common valvular heart diseases in the elderly, [27] and the commonest type of valvular heart disease in low and middle income countries. [3] In a study of 595 male elite football players aged 18–38 and 47 sedentary non-athletes, mitral regurgitation was found in 20% football players and 15% in control group. Football ...
