Question
Serious signs and symptoms of unstable tachycardia are usually NOT seen with ventricular rates less than:Question 57Answera.200 beats per minuteb.150 beats per minutec.120 beats per minuted.250 beats per minute
Solution
To determine the answer to this question, we need to understand the concept of unstable tachycardia and its associated signs and symptoms. Unstable tachycardia refers to a rapid heart rate that can lead to serious complications. In this case, we are looking for the ventricular rate at which serious signs and symptoms are usually NOT seen.
The options provided are: a. 200 beats per minute b. 150 beats per minute c. 120 beats per minute d. 250 beats per minute
To find the correct answer, we need to identify the ventricular rate at which serious signs and symptoms are typically not observed. It is important to note that the higher the heart rate, the more likely it is to cause complications.
Based on medical knowledge, a ventricular rate of 120 beats per minute is generally considered to be within the normal range. Therefore, serious signs and symptoms of unstable tachycardia are usually not seen with ventricular rates less than 120 beats per minute.
Therefore, the correct answer to this question is option c. 120 beats per minute.
