The note value of a beat will typically be that indicated by the denominator of the time signature. For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying two beats every second. While tempo is described or indicated in many different ways, including with a range of words (e.g., "Slowly", "Adagio" and so on), it is typically measured in beats per minute (bpm or BPM).

Depending on the genre of a piece of music and the performers' interpretation, a piece may be played with slight tempo rubato or drastic variances. While the ability to hold a steady tempo is a vital skill for a musical performer, tempo is changeable. Tempo may be separated from articulation and meter, or these aspects may be indicated along with tempo, all contributing to the overall texture.
In modern classical compositions, a " metronome mark" in beats per minute may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in BPM.
In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats per minute (or bpm). In musical terminology, tempo ( Italian for "time" plural tempos, or tempi from the Italian plural) is the speed or pace of a given piece.

A sustained fetal tachyarrhythmia is uncommon, affecting fewer than 1% of all pregnancies.This article needs additional citations for verification. This rapid rate may have a regular or irregular rhythm which may be intermittent or sustained.
Current international guidelines recommend for the normal fetal heart rate (FHR) baseline different ranges of 110 to 150 beats per minute (bpm) or 110 to 160 bpm.įetal tachycardia is defined as a heart rate greater than 160- 180 beats per minute (bpm). There is no consensus about the normal fetal heart rate. They continue to increase until they peak around week 9, between 140 and 170 bpm for boys and girls alike. The truth is, your baby's heart will likely start beating sometime around week 6 of your pregnancy. One may also ask, can a baby boy have a heart rate of 170? Below 140 bpm, you're carrying a boy. In low-risk pregnancies an increase in fetal heart rate from 143 (124- 171) beats per minute ( bpm) to 148 (116-191) bpm was noted after exercise while, in the high-risk pregnancy group, a transient decrease from 148 (115-170) bpm to 141 (70-180) bpm was observed. The baby's heart rate could increase all the way up to 170 bpm. A fetus's heart rate will usually range between 110 to 160 beats per minute (bpm), but it can vary throughout pregnancy.
