Subclinical atrial tachyarrhythmias, including asymptomatic atrial fibrillation, can be detected by various CIEDs including implantable cardiac monitors, dual-chamber pacemakers, dual-chamber implantable cardioverter-defibrillators, cardiac resynchronization therapy [CRT] devices, all of which allow remote rhythm monitoring.
A variety of antiarrhythmic medications (adenosine, amiodarone, verapamil, and metoprolol) also failed to control the tachyarrhythmia. Unfortunately, the conditions of the patient further deteriorate as a result of undesirable adverse effects of these antiarrhythmic medications.{Figure 1}
The primary function of ICDs is to monitor cardiac rhythm and administer high-energy shock therapy to the myocardium when a tachyarrhythmia is detected (24).
But pregnancy in Ebstein anomaly can be complicated with tachyarrhythmia or cardiac failure (13).
The new patent applications expand the scope of the Exclusive License Agreements to enable Capricor to develop new therapeutic indications for its cellular and exosome therapies in Duchenne muscular dystrophy, ventricular tachyarrhythmia, cancer and age-related disorders.
With such tachyarrhythmia, patient's heart could not compensate for its metabolic requirements reflecting as ECG changes of demand ischemia.
Recurrent AF was defined as any occurrence of sustained atrial tachyarrhythmia lasting at least 30 seconds after a postablation 3-month blanking period.
According to Oyama (2008) cyanosis is evident sign which is associated with paroxysmal arrhythmias like atrial fibrillation or ventricular tachyarrhythmia.
Tachyarrhythmia's occurred in 42% patients without any associated risk factor supporting our data.
The primary cause for this variability is differences between methods and the definition of PAF In studies that defined atrial tachyarrhythmia of any duration as PAF the PAF detection rate was higher (14,15,16).
One of these patterns in conjunction with the presence one of the following criteria: a history of documented ventricular fibrillation, a history of documented ventricular tachycardia, family history of sudden cardiac death (SCD) before the age of 45, a family history of type 1 Brugada pattern ECG changes, nocturnal agonal respiration during sleep, unexplained syncope suggestive of tachyarrhythmia, or inducible ventricular tachycardia/ventricular fibrillation during electrophysiological study.
