Sinus node sparing hybrid ablation procedure
HCA Midwest Health electrophysiologists and cardiac surgeons not only perform this advanced, highly-effective and cutting-edge surgery—they are also lead physicians of clinical studies in this revolutionary approach to arrhythmia treatment. A cardiac surgeon—in collaboration with an electrophysiologist—performs this advanced, minimally invasive sinus node sparing ablation to treat and cure inappropriate sinus tachycardia. The procedure can last two to three hours and patients usually go home in a day or two. Benefits include:
- Significantly improves heart rate
- Higher success rates than previous radiofrequency sinus node ablation
- Minimal risk of complications
- Lower risk of damaging the sinus node
- Very rare need for a pacemaker
- Reduces the need for additional surgeries

Sinus Block and Sinus Arrest - EKG (ECG) Interpretation
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.

The Pacemaker Potential of the SA Node and the AV Node
http://www.interactive-biology.com - In this episode, I talk about how the Pacemaker Potential results in the signal that causes the heart to beat. I show how the greater conductance for Sodium ions in the Pacemaker Cells in the S.A. Node cause the cells to depolarize, opening voltage-gated Calcium channels when the membrane potential reaches threshold. This results in the action potential. Then Potassium channel open, letting Potassium ions leave, repolarizing the cells.

Pacemaker Action Potential
The pacemaker action potential provides the automaticity to our cardiac pacemaker cells in the SA node. It differs from the ventricular action potential in that the depolarization occurs "automatically" almost at normal intervals. This action potential is divided into 3 phases.

Action Potential In SA Node || Primary Pacemaker of the Heart
📝 Find notes here: https://www.nonstopneuron.com/post/action-potential-in-sa-node
🌐 Explore our entire animation video library at: https://www.nonstopneuron.com/
Video Summary:
SA node is a normal pacemaker of the heart. Action potential in the SA node involves slow pacemaker potential due to slow entry of Na and Ca, upstroke due to rapid influx of Ca and Repolarization and hyperpolarization due to cessation of Ca entry and exit of K ions. Then the K efflux decreases and the slow entry of Na and Ca again brings the potential to a threshold to trigger the next action potential. Thus the SA node keeps generating action potential on its own.

Conducting system of the heart
The heart generates its own electrical impulses and has its own specially devised pathway that helps spread an action potential through the cardiac muscle. This article will explain the conducting system of the heart and touch upon the possible pathological ailments that directly relate to it.
Anatomy
The cardiac conducting system is composed of five main elements which are mentioned here in the order of which an action potential reaches them.
Sinoatrial node
The sinoatrial node is the pacemaker of the heart and is situated superior to the sulcus terminalis of the right atrium, next to the opening of the superior vena cava. This special myocardial tissue that is difficult to distinguish histologically from surrounding cardiac muscle, propagates the electrical impulses and therefore governs the sinus rhythm from minute to minute. If this node should fail, the atrioventricular node has the capacity to undertake the role of pacemaker.
Atrioventricular node
The atrioventricular node is also located in the right atrium at a level that places it posteroinferior to the interatrial septum and next to the septal cusp of the tricuspid valve. It picks up and continues the action potentials produced by the sinoatrial node and in some cases will even propagate a few of its own. Its innovative area covers the atria of the heart, just as the sinoatrial node does.
Bundle of His
The bundle of His is a specialized bundle of cardiac muscle fibers, that is seated within the interatrial septum. These fibers run along the interventricular septum to the apex of the heart, where they branch further as conducting (Purkinje) fibers that extend into the myocardium of the ventricles.
The right side has a single bundle that reaches the apex of the right ventricle before curving around it and travelling back along the right side of the heart.
The left side has an anterior and a posterior division. The anterior division cuts across the left ventricle by running through its anterosuperior wall, while the posterior division behaves as the right bundle does and circles around the left side of the heart after reaching its apex.
Purkinje fibers
The terminal strands of nervous tissue are known as the purkinje fibers and these are responsible for making sure that every small group of cells is reached by an electrical stimulus, so that a maximum muscular contraction can occur.

Video Summary:
SA node is a normal pacemaker of the heart. Action potential in the SA node involves slow pacemaker potential due to slow entry of Na and Ca, upstroke due to rapid influx of Ca and Repolarization and hyperpolarization due to cessation of Ca entry and exit of K ions. Then the K efflux decreases and the slow entry of Na and Ca again brings the potential to a threshold to trigger the next action potential. Thus the SA node keeps generating action potential on its own.
