Welcome to our Sinus Bradycardia reference page. This page provides a summary definition followed by introductions to our practice drills, quizzes, lessons and interactive guides.
Sinus bradycardia is a heart rhythm that originates in the sinus node with a rates less than 60 beats per minute.
Sinus bradycardia is a common condition in both healthy individuals, particularly athletes. It can also
occur normally during sleep.
Inappropriate Sinus Tachycardia can be caused by numerous factors, including: hypothermia, hypothyroidism, sick sinus syndrome), seizure and poisoning.
The following table summarizes the key features of an sinus bradycardia EKG rhythm strip.
A good starting point for learning EKG interpretation is our EKG Basics training course. The course provides training on the key features of an EKG tracing. These features include observing P-wave forms, measurement of EKG intervals and segments, assessment of rhythm, calculating heart rate, and the evaluation of other relevant wave segments. The arrhythmia practice drills allow students to build skills interactively.
The heart arrhythmia practice drills provide a test EKG tracing and users are asked to identify the type of arrhythmia. Many of these drills include tachycardia EKG tracings. Each answer is immediately evaluated and the correct classification of the EKG tracing is provided, along with a detailed explanation. A directory of arrhythmias is also provided.
The quiz is structured like a classroom exam. The quiz present twenty EKGs. Users answer each question and at the end of the quiz, a fully graded report is provided. This graded report provides scoring as well as the correct answer to each question. Top scores and mean scores are also provided. This quiz draws its questions from a library of over 300 EKGs, allowing users to take the quiz multiple times.
Our ECG monitor challenge uses a simulated patient monitor with moving waveform instead of a paper tracing. Twenty questions are presented, then a graded report is available.
