Company – Who is ELT?

• Innovative medical Technologies company withheadquarters in Hamburg (Germany)

• Providing leading Technologies in ECG-visualization and Stress measurement systemsin Europe and worldwide

• Funded by the government of the city ofHamburg; supported by the oldest privatebank of the world

Company philosophy

Energy-Lab Technologies is working towards one shared vision:

The aim is preventing tens of thousands of sudden, unnecessarydeaths caused by heart- and stress infarcts, sepsis and fallingasleep at the steering wheel and therefore becoming the marketleader in the field of intelligible heart- and stress-screening.

This means:

• Providing physicians and patients with innovative hardware andsoftware tools to lead healthier and better lives.

• Developing intelligent life science technologies for diagnosis andprevention of cardiovascular diseases.

Heart Screening - The “Traffic Light“ Principle

The ECP transforms the curve of an ECG into a three-dimensionalheartportrait. The „Traffic Light“ principle immediately shows thehealth level of the tested person.

Green and blue colours stand for a healthy heart with low stresslevel. Yellow and orange-like colours already call for caution(deviation from the norm ECG curve)

Red and dark purple colours immediately call for alert. Furthercheck up‘s are highly recommended!

Stress causes for the heart

Augmentation

Possible causes for high stress load:

• Chronic mental stress

• Cold or flu infection

• Cardiovascular disease

• Type II diabetes

• Drugs and certain medication (e.g. Thyroxin)

• Over-exertion and excessive training

• close correlation between reduced HRV and critical state of thepatient
