Cardiology and Sudden Cardiac Death - Chap. 8

HCM is the leading cause of cardiac sudden death in athletes under the age of 35 in the United States' population. This genetic disorder is characterized by which of the following?

Abnormal hypertrophy of the left ventricle

An athlete with a resting heart rate of 58 beats/min would have which of the following conditions documented on his or her PPE?

Bradycardia

The Wells' Clinical Prediction Rule provides a score for predisposing factors, signs, and symptoms that would determine the need for immediate referral to a physician or emergency department for which of the following conditions?

DVT

Athletes diagnosed with HCM who have an implantable cardioverter defibrillator are allowed to safely participate in competitive sports classified as high static, high dynamic by the 36th Bethesda Conference. True or False?

False

In the heart, the right and left atria pump blood into the pulmonary circuit and the right and left ventricles pump blood into the systemic circuit. True or false?

False

Over time, dynamic exercise training results in increased cardiac output. This change is a result of hypertrophy and an increase in diastolic volume, which produces an and a decreased resting heart rate.

Increased stroke volume

Aortic dissection and rupture, along with severe aortic regurgitation, account for the majority of sudden deaths related to athletes with which of the following heritable disorders?

Marfan syndrome

Which of the following conditions or events may trigger a sickling collapse in an athlete who has been diagnosed with a sickle cell trait?

Sprints or intervals at all-out exertion in hot humid conditions

The QRS complex phase on an ECG represents which of the following?

Ventricular depolarization

An athlete who receives a direct blow to the chest wall with a hard projectile may develop commotio cordis. This life-threatening condition is due to which of the following?

Ventricular fibrillation
