Sinus block is an abnormal cardiac rhythm that results from the failure of the sinoatrial node to conduct or produce action potentials. This leads to the intermediate pause of a cardiac cycle followed by an escape beat or the continuation of normal sinus rhythm. . .

⚠️ Ventricular tachycardia (VT) is a fast and abnormal heart rhythm that can be life-threatening if not treated. When the heart beats too quickly, it can’t pump blood effectively, which may lead to sudden cardiac arrest if the heart stops altogether. This #SuddenCardiacArrestAwareness Month, it’s important to know the causes and warning signs to potentially save a life. . . . . . #SuddenCardiacArrest #arrhythmias #heartrhythm #cardiacarrest #hearthealth #medicalstudent #electrophysiology | Cardi

Atrial fibrillation vs normal sinus rhythm ⠀ ⠀ ⠀ The key here is to notice the main differences in the electrical activity in the atria. ⠀ ⠀ Pay attention to how chaotic the electrical impulse is in atrial fibrillation that results in the inhibition of normal atrial contraction. ⠀ ⠀ What is a major risk for patients with atrial fib??? ⠀ ⠀ ⠀ Follow @cardiovisual for diabetes and cardiovascular educational content ❤️ ⠀ .⠀ .⠀ .⠀ .⠀ Photo credit: Navya Riju-medium.com ⠀ #cathlab #nurse #nurse💉💊 #s
