Answer:

The correct answer will be option D- blocking Cl channel.

Explanation:'

Quinidine is a stereoisomer of quinine derived from the bark of Cinchona plants which is used in the medication of the heart as class I antiarrhythmic agent. This alkaloid decreases the automaticity and increases the duration of the cellular action potential of the heart.

This alkaloid acts by blocking the neurotransmission through blocking of sodium and potassium channels responsible for the depolarization in non-nodal tissues like atrial cells, ventricular cells. This decrease in the neurotransmission of an action potential depends on the Ca⁺² ions and the quinidine can also act by blocking the Ca⁺²  channels as well as B adrenergic receptor.

Thus, option D-blocking Cl channel is the correct answer.

If u could bring back one character from greys anatomy who would it be and why?
weeeeeb [17]

Answer:

1. George O’Malley (Season 5, Episode 24)  

The world collectively gasped when George was revealed to be on the other side of the elevator doors, dressed in his Army uniform, ready to guide Izzie (Katherine Heigl) to the afterlife. This intense Season 5 ending was the audience’s first time witnessing the death of a main circle doctor, forever raising the stakes to come. From Callie recognizing the freckle, to John Doe tracing “007” into Meredith’s palm, each moment created goosebumps. The underdog of the interns didn’t deserve to go out being dragged under a bus, but it’s only fitting that he did it to save someone else’s life.  

2. Denny Duquette (Season 2, Episode 27)  

Love makes people do crazy things; but, unfortunately cutting L-Vad wires, breaking the law, and Izzie almost losing her job couldn’t save Denny Duquette from death. Isabel and Denny’s love story was the first flame that could’ve shone brighter than Meredith and Derek’s. It’s largely why the death of Denny was so heartbreakingly tragic. Although Izzie seemed to move on, Denny’s ghostly cameo in Season 5 made it clear the love story was always doomed.

The ECGs QRS complex is the stimulus for atrial diastole.<br> a. True<br> b. False
Natalka [10]

Answer:

The correct answer will be option-A

Explanation:

Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.

The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.  

As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.

Thus, option-true is the correct answer.
