Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
It is a vision that is close to normal, if in the optometric revision improves with the use of the pinhole more than three lines, the problem may be of the refractory type; If this is not corrected, it can be concluded that there is a disease.
Answer:
4,000
Explanation:
Use formula I=prt interest = principle x rate x time
Answer:
- Constituyen un alimento mas rico en vitaminas y minerales.
- Cosechas que soportan sequias y condiciones extremas.

- Caracteristicas deseables en las plantas.
- Menor uso de pesticidas.
Explanation:
Los transgenicos, o GMO, son alimentos geneticamente modificados con la finalidad de crear un producto de mayor calidad utilizando genes de otro organismo.
Los alimentos transgenicos suelen ser criticados constantemente por la poblacion ya que muchas personas creen que son dañinos para la salud. Sin embargo, estudios cientificos señalan que son sumamente beneficos en diferentes maneras. Por ejemplo:
- Constituyen un alimento mas rico en vitaminas y minerales que beneficia significativamente a poblaciones que se encuentran en pobreza.
- Cosechas que soportan sequias y condiciones extremas que una planta no transgenica no podria soportar.
- Menor costo de produccion.
- Caracteristicas deseables en las plantas. Por ejemplo, mayor tamaño o fruta mas jugosa.
- Menor uso de pesticidas. Hoy en dia, se sabe que el sobreuso de pesticidas ha ocasionado consecuencias irreparables en el medio ambiente y en la salud humana.
Answer:
Most people tend to have kinds in there early 20s or late 30s
Explanation:The average age of first-time mothers in America is now up from 21 to 26, while for fathers, it's increased from 27 to 31. This isn't just within America; women in other developed countries are waiting too with the average first birth happening for new mothers at age 31. Hope this helps :)
