ECG Machines

Two primary tests are commonly employed to assess heart health: the electrocardiogram (ECG or EKG) and the echocardiogram. These tests are typically conducted when a patient reports chest pain or when a physician observes an irregular heartbeat. In German, the term for electrocardiogram is "elektro-kardiographie," making ECG and EKG interchangeable.

The electrocardiogram (ECG) measures the heart's electrical activity and is performed by a trained ECG technician. In contrast, an echocardiogram utilizes ultrasound technology to produce a visual representation of the heart, typically conducted by an Ultrasound Technologist or Sonographer.

Generally, the ECG is the first test performed. If any irregularities are detected, the cardiovascular specialist may then recommend an echocardiogram. The ECG test involves placing small adhesive electrodes on various areas of the body, which allows the ECG machine to convert the heart's electrical signals into a series of waves recorded on paper. This process is safe, painless, and can identify a range of cardiovascular conditions, including:

• Enlarged heart

• Changes in heart wall thickness

• History of heart attack

• Irregular heartbeat

• Damaged heart tissue

The ECG can be performed while the patient is at rest or during physical activity. An Exercise ECG, often referred to as a stress test or treadmill test, measures heart rhythms during exercise, such as running on a treadmill or pedaling on a stationary bike. This test can reveal issues that may not be apparent when the heart is at rest.

Some ECG machines are now equipped with spirometry capabilities, enabling them to assess lung health by measuring airflow and evaluating various pulmonary conditions. 

Advancements in PC-based ECG systems are revolutionizing ECG technology. These modern solutions eliminate the need for bulky paper printouts and enhance the accuracy of results interpretation. Additionally, data can be stored electronically and seamlessly integrated into medical record management systems, streamlining patient care and reducing delays associated with traditional paper records.
