Che cosa vede un ECG?
L'elettrocardiogramma a riposo permette di misurare il ritmo del cuore e l'eventuale aumento della dimensione delle camere cardiache, può essere utile per individuare eventuali aritmie. L'elettrocardiogramma sotto sforzo invece può essere di aiuto per la diagnosi di patologie cardiache latenti.
Cosa significa ECG con QTc?
dove QTc è l'intervallo QT corretto per la frequenza cardiaca ed RR è l'intervallo del ciclo cardiaco misurato dall'inizio di un complesso QRS al seguente misurato in secondi, (l'intervallo QT viene invece espresso in millisecondi).
What is an electrocardiogram (ECG)?
- An electrocardiogram, commonly known as an ECG or EKG, records how your heart is functioning by measuring its electrical activity through the placement of small sensors on the chest, arms, and lower legs.
What is the difference between an ECG electrode and ECG lead?
- It is important to understand the difference between an ECG electrode and an ECG lead. An ECG electrode is a conductive pad that is attached to the skin to record electrical activity. An ECG lead is a graphical representation of the heart’s electrical activity which is calculated by analysing data from several ECG electrodes.
Why is it important to localise the leads on an ECG?
- Localising pathology on the ECG It’s important to understand which leads represent which anatomical territory of the heart, as this allows you to localise pathology to a particular heart region. For example, if there is ST elevation in leads V3 and V4 it suggests an anterior myocardial infarction (MI).
What is lifelabs ECG service?
- LifeLabs provides ECGs to patients who are stable and not clinically suspected of suffering acute myocardial infarction or a life threatening cardiac event. An ECG with LifeLabs may be ordered using the standard provincial laboratory requisitions.
