Final answer:
A wide and bizarre QRS complex with increased frequency suggests a type of tachycardia, leading to an expected increase in heart rate (pulse). This signifies a potentially dangerous heart rhythm and immediate medical attention is needed.
Step-by-step explanation:
If the QRS complex on an electrocardiogram (ECG) appears wide and bizarre, and there is an increased frequency between the QRS complexes, this typically indicates an abnormal heart rhythm, potentially a type of tachycardia. Normal QRS duration is usually between 0.06 and 0.10 seconds; a wider QRS suggests a disturbance in the heart's electrical conduction system. Coupled with increased frequency of the QRS complexes, which means there are more heartbeats over a set period of time, you would expect the heart rate (pulse) to be higher than normal, indicating an elevated risk of complications such as reduced cardiac output, heart failure, or more serious arrhythmias like ventricular tachycardia. Immediate medical evaluation is important to diagnose the specific condition and initiate appropriate treatment.
