Enter the Ace of Hearts: Cardiovascular Board Review. We've taken all the main content of a traditional board review course and packed it into an easy-to-carry and use flashcard format. You'll realize that there are moments in your busy day that can be stolen to study. Imagine this, you're waiting for a patient to roll into the cath lab or your office patient is being triaged by the medical staff. You have 5 minutes. You take out a flashcard from your scrubs or white coat and review the entire section on pacemakers, inclusive of the major clinical trials you need to know, complete with engaging questions and answers. By the time your patient is ready for you, you've covered 5 flashcards, which is the equivalent of listening to an hour of lectures. You put the flashcards back into your pocket, take a deep breath, and walk into your patient's room.
