and semilunar valves. Atrioventricular valves. The atrioventricular (AV) valves are located in the middle of the heart between the atria and ventricles and only allow blood to flow from the atria into the ventricles. The AV valve on the right side of the heart is called the tricuspid valve because it is made of three cusps (flaps) that separate to allow blood to pass through and connect to block regurgitation of blood. The AV valve on the left side of the

Analyse av “Gugg” (Ingens‚ 1992) Lars Saabye Christensen “Gugg” er skrevet av forfatteren Lars Saabye Christense. Den er en av novellene fra Christensens første novellesamling “Ingens” som ble utgitt I 1992. Novellen begynner i in medias res‚ hvor han etter 20 år ser damen han for mange år siden hadde såret. Han føler fortsatt skam over det han har gjort. Teksten er ikke kronologisk fortalt. Novellen avslutter der vi begynte‚ og undeveis får vi en forklaring på hvorfor jeg-personen fortsatt

Anatomy The pertinent anatomy for cardiac pacing includes the sinoatrial (SA) node‚ the atrioventricular (AV) node‚ and the His-Purkinje system (Figure 1.1). The SA node is located at the superior aspect of the crista terminalis (not pictured)‚

Kay has a relationship with a grower who grows two types of wine grapes‚ a Chardonnay and a generic white grape. AVS buys the grapes at the point that they have ripened on the vine. AVS is responsible for harvesting the grapes and all further processing of the grapes into wine. In 2010‚ AVS earned an operating margin of almost $100‚000 on sales of $848‚000‚ for an

to understand. 2- What exactly is being “blocked” in heart block? The signal from the SA node is trying to get to the AV node‚ and it’s being slowed down‚ or blocked altogether – it’s having a hard time getting through. The result is that the SA signal going through the atria makes a normal P wave‚ but if that signal doesn’t trigger a response from the AV node‚ no QRS gets produced – so you’ll see a P wave that isn’t followed by a QRS. The QRS represents ventricular depolarization –

o The P wave represents the depolarization of the atria (passage of an electrical impulse through the atria)‚ causing atrial contraction. o The PR interval represents the time period for the impulse to spread through the atria‚ atrioventricular (AV) node‚ bundle of His‚ and Purkinje fibers. o The QRS complex represents depolarization of the ventricles (ventricular contraction). o The QRS interval represents the time it takes for depolarization. o The ST segment represents the time between ventricular
