Bradycardia And Tachycardia Flashcards
(25 cards)
What is bradycardia?
Bradycardia is a slower than normal heart rate, typically defined as a heart rate of less than 60 beats per minute.
What is tachycardia?
Tachycardia is a faster than normal heart rate, typically defined as a heart rate of more than 100 beats per minute.
True or False: Bradycardia always indicates a health problem.
False. Bradycardia can be normal in some individuals, especially athletes.
Fill in the blank: The normal resting heart rate for adults typically ranges from _____ to _____ beats per minute.
60 to 100
What are some possible causes of bradycardia?
Common causes include heart disease, certain medications, and electrolyte imbalances. COVID-19, drug toxicity, electrolyte abnormality, peri-atrioventricular inflammation as in Lyme disease, rheumatic fever, myocarditis, and transient injury to the conduction system during open heart surgery.
What are some common causes of tachycardia?
Common causes include stress, anxiety, fever, anemia, and heart conditions.
Multiple choice: Which of the following is a type of tachycardia? A) Atrial fibrillation B) Bradycardia C) Ventricular fibrillation D) Asystole
A) Atrial fibrillation
What is the primary treatment for symptomatic bradycardia?
The primary treatment may include the use of atropine or a pacemaker.
What is the primary treatment for tachycardia caused by anxiety?
The primary treatment may include relaxation techniques and medications such as beta-blockers.
True or False: Both bradycardia and tachycardia can be life-threatening.
True. Both conditions can lead to serious complications if not treated.
What is the difference between supraventricular and ventricular tachycardia?
Supraventricular tachycardia originates above the ventricles, while ventricular tachycardia originates in the ventricles.
Fill in the blank: An electrocardiogram (ECG) is used to diagnose _____ and _____.
bradycardia and tachycardia
What symptoms might a person with bradycardia experience?
Symptoms may include fatigue, dizziness, fainting, and shortness of breath.
What symptoms might a person with tachycardia experience?
Symptoms may include palpitations, chest pain, dizziness, and shortness of breath.
Multiple choice: Which heart rate indicates bradycardia? A) 50 bpm B) 75 bpm C) 110 bpm D) 90 bpm
A) 50 bpm
Multiple choice: Which heart rate indicates tachycardia? A) 55 bpm B) 65 bpm C) 85 bpm D) 120 bpm
D) 120 bpm
True or False: All cases of tachycardia require immediate medical attention.
False. Some cases of tachycardia are benign and do not require immediate treatment.
What is one potential complication of untreated bradycardia?
One potential complication is syncope (fainting) due to insufficient blood flow to the brain.
What is one potential complication of untreated tachycardia?
One potential complication is heart failure or stroke due to ineffective heart pumping.
Fill in the blank: The heart’s electrical system regulates the _____ and _____ of heartbeats.
rate and rhythm
What role do beta-blockers play in managing tachycardia?
Beta-blockers slow down the heart rate and reduce the heart’s workload.
What lifestyle changes can help manage bradycardia?
Lifestyle changes include regular exercise, a healthy diet, and avoiding medications that can lower heart rate.
What lifestyle changes can help manage tachycardia?
Lifestyle changes include stress management, avoiding stimulants, and regular physical activity.
True or False: A heart rate monitor can help track bradycardia and tachycardia.
True. Heart rate monitors can provide real-time data on heart rate changes.
