31K views · 362 reactions | #Sinoatrial (SA) node #arrhythmias, also known as sinus node dysfunction or sick sinus syndrome, occur when the heart's natural pacemaker (SA node) doesn't function properly, leading to abnormal heart rhythms. These arrhythmias can include slow heart rates (bradycardia), fast heart rates (tachycardia), or a combination of both, potentially causing symptoms like lightheadedness, dizziness, and fatigue. #education #ECG #doctor #medicalstudent #nurses | Med G | Facebook

@medgrindfit_ on Instagram: "In the world of emergency medicine, a few seconds can change everything - and Adenosine is the perfect example of that. > This life-saving drug works like a magic reset button for the heart, used in cases of Paroxysmal Supraventricular Tachycardia (PSVT) - when the heart suddenly starts racing way too fast. •Adenosine acts on the A1 receptors in the AV node, temporarily blocking conduction through it. This brief pause allows the heart’s natural pacemaker - the SA nod

Medical | Health | Anatomy on Instagram: "Cardiac foci are abnormal electrical trigger points in the heart that generate impulses outside the normal pacemaker, the sinoatrial (SA) node. These ectopic signals can disrupt the heart’s regular rhythm and are a common cause of arrhythmias. Biological mechanism: Normally, the SA node initiates each heartbeat in a coordinated wave. In cardiac foci, other heart cells—often in the atria, ventricles, or pulmonary veins—become electrically active on their
