In our part 3 of EKG rhythm interpretation, you will get a quick rundown on the anatomy of the heart and how a typical rhythm malfunctions, progressing to the different types of heart rhythm abnormalities. The Heart Set-Up First, we go to the basics – the anatomical parts of the heart mainly involved in transmitting impulses. Left and right atriums
When talking about heart conductivity, the first thing that comes to mind is the rate in which the heart contracts – either too much or too little. If the heart is contracting at an increased, irregular, and uncontrollable speed, then what we usually give is a rate-control drug. Rate-control drugs are your: Beta-blockers Calcium-channel blockers These drugs affect the electro-excitability
Do you have difficulty pinpointing and memorizing the different types of insulin with their peak, onset, and duration? Here’s a nifty trick for you – we will show you how to effortlessly recall the peak, onset, and duration of the different types of insulin. Remember, the peak, onset, and duration of insulin is one of the most confusing topics in
Blood urea nitrogen (BUN) and creatinine levels are frequently prescribed by health care providers (HCP). And as a nursing student, it’s essential to understand the importance of interpreting these BUN and creatinine lab results accurately. BUN measures the amount of nitrogen in the blood that comes from urea, a waste product of protein metabolism. On the other hand, creatinine is
In this lecture we are going to talk about the following: HemodynamicsSWANS catheterCardiac outputPulmonary artery wedge pressureAtrium pressure (central venous pressure) Hemodynamics The main reason for to run a hemodynamics test is to measure four different things: Vascular capacity – how much pressure is going into the heartBlood volume – how much volume of blood the heart should pushPump effectiveness
Calcium channel blockers are antihypertensive medications that technically reduce hypertension or blood pressure; thus, relieving stress from the heart. How does one quickly spot a calcium channel blocker? More often than not, calcium channel blockers end in “-pine.” Not to be confused with another antihypertensive medication known as beta-blockers that end in “-lol.” The most popular calcium channel blocker used
What is important in a fetal heart assessment? Let’s start with the basics. In fetal heart monitoring, two monitors are placed on the mother’s abdomen. One will measure the contractions, while the other will measure the fetal heart rate or tones. Focusing on the fetal heart rate, certain classifications tell whether the heart rate is: Reassuring Elevated Early deceleration (bradycardic)
