2. HBI-3000 - Wikipedia

   en.wikipedia.org/wiki/HBI-3000

   HBI-3000 suppresses early afterdepolarizations (EADs; a change in the normal net flow of ions during repolarization), does not produce any electrical abnormalities, and displays minimally pronounced prolongation of APD during a slow heart rate (i.e. stimulated at a slower frequency). Pronounced prolongation of APD during a slow heart rate can ...

3. Antiarrhythmic agent - Wikipedia

   en.wikipedia.org/wiki/Antiarrhythmic_agent

   Reduce ventricular rate in patients with atrial fibrillation; V Adenosine; Digoxin; Magnesium sulfate; Work by other or unknown mechanisms Contraindicated in ventricular arrhythmias; Adenosine is used to treat supraventricular tachycardias, especially in heart failure and atrial fibrillation [9]

4. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

5. Potassium channel blocker - Wikipedia

   en.wikipedia.org/wiki/Potassium_channel_blocker

   Reverse use dependent drugs that slow heart rate (such as quinidine) can be less effective at high heart rates. [11] The refractoriness of the ventricular myocyte increases at lower heart rates . [ citation needed ] This increases the susceptibility of the myocardium to early Afterdepolarizations (EADs) at low heart rates.

6. Ivabradine - Wikipedia

   en.wikipedia.org/wiki/Ivabradine

   Blocking this channel reduces cardiac pacemaker activity, selectively slowing the heart rate and allowing more time for blood to flow to the myocardium. [15] [16] By inhibiting the I f channel, ivabradine reduces the heart rate and workload on the heart. This is relevant in the usage of the medication to treat angina as well as congestive heart ...

7. Automated external defibrillator - Wikipedia

   en.wikipedia.org/wiki/Automated_external...

   An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...

8. Amiodarone - Wikipedia

   en.wikipedia.org/wiki/Amiodarone

   Hypothyroidism (slowing of the thyroid) occurs frequently; in the SAFE trial, which compared amiodarone with other medications for the treatment of atrial fibrillation, biochemical hypothyroidism (as defined by a TSH level of 4.5–10 mU/L) occurred in 25.8% of the amiodarone-treated group as opposed to 6.6% of the control group (taking placebo ...

9. Wandering atrial pacemaker - Wikipedia

   en.wikipedia.org/wiki/Wandering_atrial_pacemaker

   Both arrhythmias have at least 3 different P-wave morphologies in a single ECG lead, but the heart rate is different. When the heart rate is lower than 100 beats per minute, the heart rhythm is considered wandering atrial pacemaker. When the heart rate is greater than 100 beats per minute, the heart rhythm is considered multifocal atrial ...
