Cardiographs can be single-channel and multi-channel. In the first case, the device records cardiograms in several leads sequentially. These are very simple devices by design. Due to their light weight, which rarely exceeds 1 kg, ability to work from battery, and mobility, they are most often used in ambulances. Single-channel electrocardiographs can be purchased very […]

ECG is a record of the changes in electric potentials occurring during the contraction of the heart. Electrocardiography forms the basis of many other diagnostic investigations – Holter monitoring, bicycle ergometry, transoesophageal recording of ECG, pharmacological tests with ECG, remote ECG and monitoring in intensive care or during operations. Electrocardiography is absolutely harmless and painless […]

In routine clinical practice, Holter (aka 24-hour) ECG monitoring is widely used. Yet, what are the advantages of multi-day ECG monitoring over Holter monitoring? Let’s figure it out! The Purpose The need for long-term ECG monitoring is primarily due to the presence of rare (1-2 times per week or less) arrhythmic events or clinically significant […]

As Wendell Willkie once mentioned:” There are no distant places any longer: the world is small and the world is one.” This expression accurately stresses what is happening in almost all spheres of human activity, including the healthcare provision. Indeed, telemedicine has revolutionized healthcare delivery, making medical services remote and instant. The contemporary paradigm which […]

The article discusses the evolution and significance of ECG systems in cardiac monitoring. It highlights their role in diagnosing and preventing heart conditions, the advancements by Norav Medical in ECG technology, and the future potential of AI and wearable devices in enhancing cardiac health management. In response to the increasing demand for precise and timely […]

Stress tests (ST) are a common and accessible method for diagnosing and examining patients with cardiovascular diseases. Physical stress tests are conducted to diagnose coronary pathology, detect hidden heart rhythm and conduction disorders, determine the level of physical performance (tolerance to physical exertion), and monitor the effectiveness of treatment and rehabilitation measures. Research protocol 1) […]

How does a stress test work? Usually, cardiac stress tests imply making the heart beat harder and faster by walking on a treadmill or riding a stationary cycle. Doctors assess your response to increased workload by measuring:    Blood pressure.    Heart rate.    Oxygen level.    Electrical activity in your heart.    How hard your heart is working compared […]

When one recalls the fundamental contemporary diagnostic tools, Electrocardiography (ECG) is one of the first to come to mind. Why, you may ask? Well, that is because of the accuracy and simplicity of the technique. Healthcare professionals for decades have used ECG readings to identify the patient’s cardiac condition, especially in emergency settings. The correct […]
