What evaluation must be conducted annually for drivers with cardiovascular conditions?

For drivers with cardiovascular conditions, an annual evaluation is crucial to ensure their fitness for duty and safety on the road. This evaluation often involves several specific tests to comprehensively assess their heart health.

A cardiac ultrasound can provide valuable information about the structure and function of the heart, helping to identify any abnormalities that could impact a driver's ability to operate a vehicle safely.

An electrocardiogram (ECG) is another important tool; it measures the electrical activity of the heart and can detect arrhythmias, previous heart attacks, or other cardiac issues that might affect driving capabilities.

A Holter monitor, which is a portable device that records the heart's rhythm for a 24-hour period, can help detect irregular heart rhythms that may not show up during a standard ECG.

Given the potential complexities of cardiovascular conditions, it is often necessary to use multiple diagnostic tools to have a complete picture of a driver's cardiac health. Therefore, the correct answer reflects the comprehensive approach required for evaluating drivers with these conditions annually, indicating that all of the mentioned evaluations are part of the assessment process.
