Considering symptomatic bradyarrhythmia
and diffuse conducting system disease, decision of permanent pacemaker (PPM) implantation was taken.
Isoproterenol is a nonselective beta-adrenoceptor agonist and an effective medication for bradyarrhythmias
. We used this agent temporarily to increase the patient's heart rate, pending the placement of a permanent pacemaker.

," Pacing and Clinical Electrophysiology, vol.
Previous studies suggested that treatment for AD with acetylcholinesterase inhibitors might result in bradyarrhythmias
even needing pacemaker implantation [6,7,21].
Such serious arrhythmias--as high-grade atrioventricular blocks and bradyarrhythmias
followed by syncopal episodes--occasionally occur during an attack of Prinzmetal angina (Matsue et al 2012; Shah 2010).
Sick sinus syndrome produces a variety of EKG manifestations consisting of atrial bradyarrhythmias
, atrial tachyarrhythmias, and alternating bradyarrhythmias
and tachyarrhythmias as in tachycardiabradycardia syndrome .
Pacemakers are indicated in patients with certain symptomatic bradyarrhythmias
caused by SND and in patients with frequent, prolonged sinus pauses .
Exclusion criteria included any alteration in the physical exam other than syncope, such as congenital heart disease, valve insufficiency, systolic dysfunction (considered when fractional shortening <20%) or increased cardiac dimensions during the echocardiographic evaluation and bradyarrhythmias
at the electrocardiographic evaluation.
A battery of noninvasive tests was performed in order to assess for common cardiac manifestations of Chagas disease, including, but not limited to, left ventricular dilatation and dysfunction, wall motion abnormalities, aneurysms, diastolic dysfunction, pathologic bradyarrhythmias
and tachyarrhythmias, and ischemic heart disease.
The Third Universal Definition of MI task force document defines T2MI in instances of myocardial injury with necrosis where a condition without an acute atherothrombotic event contributes to an imbalance between myocardial oxygen supply and/or demand, such as coronary endothelial dysfunction, coronary artery spasm, coronary embolism, tachyarrhythmias, bradyarrhythmias
, anemia, respiratory failure, hypotension, and hypertension with or without left ventricular hypertrophy (9).
The most common CHD patients associated arrhythmias are AF and PVCs which would make the motion beat either slower (commonly known as bradyarrhythmias
) or faster (commonly known as tachyarrhythmias).
They cover normal ECG, bradyarrhythmias
, tachyarrhythmias, miscellaneous arrhythmias and cardiac conditions, electrolyte disturbance and the ECG, and emergency algorithms.
include sick sinus syndrome, which causes pauses due to sinus arrest and a subsequent fall in cardiac output.
: disorders of sinus node function and AV conduction disturbances.
Attributes: duration of fever: presence of prolonged pyrexia (>14 days' duration); fever grade: high grade fever >101[degrees]F; risk factors: presence of predisposing cardiac condition like CHD orbeing IDU apart from RHD; ECG: presence of tachy/ bradyarrhythmias
; RF: rheumatoid factor positive; cultures: blood cultures positive compatible to modified Duke's criteria; iron saturation; presence of iron deficiency; vegetation size: vegetations >10 mm size in their long axis; vegetation site: right sided chamber/valvular lesions.
