An electrocardiogram (EKG or ECG) is a simple and non-invasive test that measures the electrical activity of the heart. Every heartbeat is triggered by an electrical impulse, and an EKG records this activity as wave patterns on a monitor or paper. These wave patterns can reveal how well the heart is functioning and can help identify irregularities in the heart's rhythm, structure, or electrical conduction. The test provides crucial insights into the heart’s health and is often used to diagnose or monitor various cardiac conditions.

The EKG works by placing electrodes on the skin, usually on the chest, arms, and legs. These electrodes detect the electrical signals generated by the heart with each beat. The information is then transmitted to an EKG machine, which interprets the signals and produces a graph representing the heart's electrical activity over time. The different parts of the graph, such as the P-wave, QRS complex, and T-wave, correspond to different stages of the heart's electrical cycle, helping doctors identify potential abnormalities.

Migraines can have a profound impact on daily life and productivity, particularly for individuals who experience frequent or chronic episodes. The intense pain, sensitivity to light and sound, and accompanying symptoms like nausea and fatigue can make it difficult to carry out everyday tasks, including work, household responsibilities, and social interactions. Many people with migraines find that they need to take time off from work or school during an attack, which can lead to missed deadlines, decreased performance, and, in some cases, job insecurity. The unpredictability of migraines can also make it challenging to plan activities or maintain a consistent routine.

Beyond the immediate impact of the migraine episode itself, many individuals experience lingering effects, such as fatigue or mental fogginess, even after the headache subsides. This postdrome phase, often referred to as a "migraine hangover," can further affect cognitive function and reduce productivity for hours or even days. Migraines can also take a toll on emotional well-being, contributing to anxiety, depression, and social isolation due to the unpredictability and debilitating nature of the condition. Addressing migraines effectively, through both medical treatment and lifestyle changes, is essential for maintaining quality of life and minimizing their impact on daily activities.
