Chap 5 - Cardiology Diseases Part 2

Question 0

A repeating pattern of one normal contraction followed by one premature contraction.

Answer 0

Bigeminy

Question 1

Arrythmia in which there are one or more extra contractions within a cardiac cycle.

Answer 1

Premature contraction (Extrasystole)

Premature Atrial Contractions (PACs)

Premature Ventricular Contractions (PVCs)

Question 2

A repeating pattern of two normal contractions followed by one premature contraction.

Answer 2

Trigeminy

Question 3

Two premature contractions occurring together.

Answer 3

Couplet

Question 4

Arrhythmia in which bradycardia alternates with tachycardia. Occurs when the sinoatrial node and ecoptic sites elsewhere in the myocardium take turns being the heart’s pacemaker.

Answer 4

Sick sinus syndrome

Question 5

Arrhythmia in which there’s fast but regular rhythm (up to 200bpm).

Answer 5

Tachycardia

Question 6

Occurs when the ectopic group of cells is located superior to the ventricles.

Answer 6

Superventricular tachycardia

Question 7

Is an episode or tachycardia that occurs suddenly and then goes away without treatment.

Answer 7

Paroxysmal tachycardia

Question 8

Area of dilation and weakness in the wall of an artery. Can be congenital or where arteriosclerosis has damaged the artery. With each heartbeat, the weakened artery balloons outward. These can rupture without warning.

Answer 8

Aneurysm

Question 9

Aneurysm that enlarges by tunnelling between the layers of the artery wall.

Answer 9

Dissecting aneurysm

Question 10

Progressive degenerative changes that produce a narrowed, hardened artery. Begins with a small tear in the endothelium that’s caused by chronic hypertension. Then LDLs in the blood deposit cholesterol and form a Atheroma or Atheromatous plaque inside artery. Plaque grows and narrows artery and walls become hardened and nonelastic.

Answer 10

Arteriosclerosis

Hardening of the arteries
