ECG Düsseldorf
The electrical fingerprint of your heart
The 12-lead ECG is the basis of all cardiological diagnostics. It records the electrical currents that trigger each of your heartbeats. PD Dr. med. Raphael Bruno reads far more than just the rhythm from these curves: We detect circulatory disorders, undetected inflammation or thickening of the heart muscle. Fast, painless and absolutely precise, it forms the foundation for your heart health.

Electrical precision: 7 insights from the resting ECG
Writing an ECG only takes a few seconds - interpreting it correctly requires years of experience. While computer programs often produce false alarms, analyzing PD Dr. med. Raphael Bruno every jag and every wave personally. We look for the subtle nuances that indicate early risks long before you feel any symptoms.
- Rhythm check: Differentiation between healthy sinus rhythm and complex cardiac arrhythmias.
- Exact determination of the heart rate to detect phases that are too slow (bradycardia) or too fast (tachycardia).
- Early vascular risk detection: Precise vascular age measurement for early identification of hidden risks of cardiovascular disease.
- Layer type determination: Determination of the electrical heart axis, which gives an indication of the position and strain on the heart.
- Hypertrophy sign: Detection of thickening of the heart muscle, which is often caused by years of high blood pressure.
- Ischemia search: Identification of acute or past circulatory disorders (heart attacks) on the basis of ST segment changes.
- Interval measurement:Analysis of the electrical recovery time (QT time), important for avoiding drug-related side effects.
For whom is the 12-lead ECG relevant?
As a fundamental component of cardiology, the ECG is part of almost every visit to the doctor. It provides immediate information about the current condition of the heart.
At the check-upAs a basic examination for every patient over 35 to document the status quo of heart health.
For heart palpitationsTo clarify whether these are harmless extra beats or atrial fibrillation requiring treatment.
Before operationsFor risk assessment of anesthesia capability (surgical clearance) prior to surgical procedures.
For chest painFor immediate exclusion or detection of an acute myocardial infarction or angina pectoris.
What we measure - ECG parameters in detail
The ECG is a graphical representation of the heart's electrical system. Each wave on the paper corresponds to a specific phase of the heartbeat - from the filling of the atria to the vigorous pumping of the ventricles. Here you can see what PD Dr. med. Raphael Bruno reads from the curves.
| Measured value & phase | Diagnostic significance |
| P-wave | Atrial activityShows the excitation of the atria. Changes here often indicate atrial fibrillation or an enlargement of the atria. |
| PQ time | Transition timeThe time it takes for the impulse to travel from the atrium to the ventricle. Prolongations indicate AV blockages. |
| QRS complex | Chamber excitationThe heart contracts. Widenings signal conduction disturbances such as a bundle branch block. |
| ST route | CirculationThe most important marker for myocardial infarction. Elevations or depressions indicate acute oxygen deficiency. |
| T-shaft | Recovery phaseThe regression of the excitation. Changes may indicate electrolyte disturbances (e.g. potassium) or old infarcts. |
| QT duration | Electrical stabilityA prolonged QT time can be a risk for dangerous arrhythmias, often triggered by certain medications. |

Frequently asked questions about the electrocardiogram
Early clarification of symptoms or risk factors is the key to long-term heart health. Our cardiology practice in Düsseldorf offers you the right specialized care for every need.
No, absolutely not. The ECG is a purely passive measurement. We do not conduct any current into the body, but only measure the weak electrical signals that your heart generates itself. It is completely painless and risk-free.
Smartwatches usually only record a 1-channel ECG. This is often enough to detect atrial fibrillation, but is „blind“ to many other conditions such as circulatory disorders or wall thickening. A medical 12-lead ECG offers a 360-degree view of the heart.
No. However, it helps not to use any very greasy body lotions in the breast area on the day of the examination, as otherwise the adhesive electrodes may adhere less well.
Writing the ECG only takes a few seconds (approx. 10-30 seconds). With preparation (attaching adhesive electrodes) you are usually finished in under 10 minutes.
We use 10 cables for 12 leads. Think of it as 12 cameras filming your heart from different angles. This is the only way we can localize exactly where in the heart there is a problem (e.g. anterior wall vs. posterior wall).
Yes, heart attacks often leave typical scar patterns on the ECG (e.g. pathological Q-waves), which are still visible years later.

Relaxed examination in the Stahlhof
Even if the ECG is a routine examination, we take time for you. In our air-conditioned practice rooms, the ECG is written while you are lying down and relaxing. Thanks to state-of-the-art digital networking PD Dr. med. Raphael Bruno The doctor immediately sees the curves on his monitor and can discuss the results with you in detail during the same appointment. No waiting time for findings, just immediate clarity.
