In an arrhythmia, these electrical signals travel too fast, erratically, and chaotically.

👩🏽⚕️ Additional questions (FAQs)
💬 Is Sotalol (Sotalol / Betapace) a special heart pill given to patients with heart failure?
Yes! This is not a normal blood pressure pill! It also lowers blood pressure (Beta-blocker), but it is mainly used as an extremely powerful drug (Antiarrhythmic) to gradually bring the heart rhythm back to the normal rate (Arrhythmias/Atrial Fibrillation), which is a life-threatening condition in which the heart's electrical rhythm changes and beats abnormally/rapidly.
💬 How does this drug (Sotalol) change the electrical defect/abnormal rhythm in the heart?
In a wonderful way! The heart beats fast because the electrical signal system in it is 'shorted'! This pill (Dual action) attacks from both sides! 1. As a Class II (Beta-blocker), it cuts off the adrenaline message coming to the heart and relaxes the heart. 2. As a Class III, it blocks the 'Potassium Channels' in the heart muscles. Then, the heart that is beating like crazy (by extending the Action Potential Duration) gets a lot of space/rest before the next beat and the rhythm becomes normal.
💬 What are the most dangerous risks (Black Box Warnings) when taking these pills?
The biggest surprise is that this does not stop everyone's heart rate! For some people, it can cause new abnormal heart rhythms, which can lead to cardiac arrest (Torsades de pointes / Proarrhythmia), which can be fatal. Therefore, this pill is given initially (for 3 days) after admission to the hospital and continuous (EKG/ECG) heart scans! Also, this (Beta-blocker) can cause the lungs of people with asthma/wheezing to become blocked and die.
