which of the following cardiac dysrhythmias has the greatest chance of deteriorating into a pulseless rhythm?
amm1812

Ventricular tachycardia has the greatest chance of deteriorating into a pulseless rhythm in cardiac dysrhythmias.

A cardiac dysrhythmia may also be called a cardiac arrhythmia or an irregular heart rhythm.Cardiac dysrhythmia (arrhythmia) is an irregular or irregular heartbeat. If you have dysrhythmia, your heart may beat too fast or too slowly. Or your heart rhythm may be disrupted, leading you to feel like your heart is skipping a beat. Although dysrhythmias can be harmless, they can cause serious health problems if left untreated. The words dysrhythmia and arrhythmia are different especially in linguistic sense. A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. Heart arrhythmias occur when the electrical signals that regulate the heartbeat do not work properly.

What contributes to cell membrane fluidity? Proteins and lipids exist as separate but loosely attached molecules that can move a
Charra [1.4K]

Answer:

Proteins and lipids exist as separate but loosely attached molecules that can move around

Explanation:

Cell membranes are mainly composed of lipids, proteins, and also carbohydrates. Phospholipids are the most abundant type of lipid and the main constituent of the cell membranes. Membrane proteins are divided into two types according to their interactions with the cell membrane: 1-integral (intrinsic) and peripheral (extrinsic) proteins. These peripheral proteins are loosely attached by ionic bonds or calcium bridges with the phosphate heads of the phospholipids; whereas integral membrane proteins contain side chains that interact with fatty acyl groups of the phospholipids. Cell membrane fluidity indicates how easily lipids (e.g., phospholipids and cholesterol) and proteins (e.g., intrinsic proteins) diffuse laterally in the cell membrane. This fluidity is affected by the amount of cholesterol, temperature, and the ratio of unsaturated to saturated fatty acids. Saturated fatty acids have no double bonds in the hydrocarbon chain, whereas unsaturated fatty acids have at least one double bond (these double bonds increase fluidity). Moreover, higher temperatures increase membrane fluidity, whereas cholesterol molecules function to regulate membrane fluidity: at high temperatures cholesterol molecules stabilize the membrane, whereas at low temperatures intercalate between phospholipids, thereby preventing them from clustering together.
