How to Calculate Heart Rate from ECG

Guru Kowlgi, MD on Instagram: "ECG 112: Why are beta blockers effective in Long QT syndrome? 1. Even though beta blockers slow the heart rate down and can prolong the QT interval, they help with stabilizing the repolarization by reducing the beat to beat variability. 2. They also reduce the frequency of PVCs which can trigger early after depolarization which is the main mechanism for ventricular arrhythmias in long QT syndrome. 3. The concept of regularizing the repolarization to reduce proarrhy

Scott Freda on Instagram: "Excessive doses of Benadryl (diphenhydramine) can cause serious, life-threatening heart problems, including severe arrhythmias, tachycardia (rapid heart rate), prolonged QT interval, widened QRS complex, and cardiac arrest. High doses, often associated with misuse, can also lead to seizures, coma, or death, prompting warnings from the FDA. Health alert by online health coach Scott Freda"
