🙋‍♂️This video shows a modified Valsalva maneuver being used in the emergency treatment of stable SVT 🫀(supraventricular tachycardia)! Learn more👇 This awesome ER team was able to temporarily convert a stable paroxysmal SVT back into sinus rhythm! This is a beautiful example of how manipulating nervous system & leveraging physiology can be used as a simple, cost-free treatment. So, how does it work: The modified Valsalva can be divided into 3 phases: * Phase 1: Increasing intrathoracic pressure: At beginning of video, you’ll see patient perform a standardized ‘strain’ (blowing into a 10mL syringe) for about ~15 seconds while sitting up or in a semirecumbent position. Bearing down like this contracts thoracic & abdominal muscles & causes a drop in blood flow back to the heart (decreased preload) & brain. This drop stimulates baroreceptor reflex & compensates by triggering the sympathetic nervous system (stress response) in an attempt to raise BP, cardiac output & peripheral vascular resistance. * Phase 2: Dropping intrathoracic pressure: After the ~15 second strain, just prior to being laid flat (or simultaneously), patient will stop blowing into syringe, this causes pressure in thorax to suddenly decrease, subsequently increasing blood flow back to heart & increasing preload-> leading to opposite of phase 1: a compensatory increase in parasympathetic (vagal) activity aimed at decreasing heart rate + increasing relaxation response. * Phase 3: Laying flat & raising legs to 45 degrees: This postural modification causes more blood flow back to heart, leading to increase in stroke volume & cardiac output. Causing further vagal - parasympathetic - stimulation, which compensates for these changes by telling body to decrease the heart rate (SA node) -> this can convert patient back into sinus rhythm!

South African Doctor Prof 'Mashudu Tshifularo' became the first Surgeon on Earth to successfully perform surgery to cure deafness. Hats off, please! ❤️

Giving IV fluids and diuretics at same time 😅
